THIS Is Why People Screw Up JDM Engine Swaps! // Project MR2 Turbo 

What’s most impressive is how you were able to write on a dry erase board that neat and straight.

Since discovering this channel (I watch EVERY video btw😁)...its one of the few things that actually makes me genuinely happy...I love your sense of humor...thank you for just being you🙂💙

I’ve come to the conclusion that you’re some sort of a car genius! Maybe just a plain genius! Oh, and you’re funny too!

The level of patience this must take is astounding. You never fail to impress.

Persistence will pay off; you're the type that doesn't give up easily. 🚘👍

The STA circuit does go through the clutch switch, but it as an input to the ECU is really only as a check, allowing the ECU to know the engine should be cranking by way of the starter motor. Kind of similar function to when your Forrester threw crank/cam sensor faults when the starter went out, it's version of that STA circuit told the ECU to be looking for those signals, which it wasn't seeing. I personally nerd out hard on this kind of work, but you did a most excellent job of keeping it interesting for about everyone else. As long as you include the appropriate punctuation, in your head, while talking, sentences can go on forever...

I'm constantly amazed at how much work you get done - and then add all the filming and editing tasks to that. Very impressive!

Attention to detail that I'm simply incapable of. Mass respect.

These are so relaxing, it's nostalgic from doing this 30 years ago with haltechs and yet therapeutic seeing actual great OCD attention to detail without corner cutting! ❤️👍

I have just finnished the loom on my escort rs turbo. I havent even filmed it because it would just be me swearing at it for 3 days 🤣

I watch all of your video's and the attention to detail, pride of ownership, and incredible organization during the project has truly inspired me.

Your ability and dedication to work through every nuance is why you (and your vehicles) are successful. Keep up the inspiring work.😁👍

AWESOME! SO IMPRESSED! SARAH NAILS IT! Brilliant, persistent, detailed hard work. Not flashy but essential for a successful project! Sarah's the BEST.

This was outrageous.... you are like a Swiss army knife, you are able to do so many things all enclosed in one body. You never cease to AMAZE me, I really enjoy your videos they are informative , funny, and laced with self deprecation that we all understand.

Aaaayyyyyy. Hit refresh and got a Sarah video! Let's goooo

I can't be the only one that found her explanations relatively easy to follow and understand can I? Sarah you make me suddenly want to rewire the harness on my wife's truck. You make pain and suffering look so rewarding.

I’ve greatly missed you jousting with your MR2 😃 always educational to hear your thought processes and your OCD driven attention to detail is impressive to say the least 😊 Just the greatest content creator on RU-vid 👍

Don't worry Sarah, from head to toe you don't have any unflattering angles!

Trust me Sarah, you don't have any unflattering body angles, they're all pretty well perfect!!!

This a great showcase of why we follow you. I could watch this stuff as much as the great car reviews. The range of content keeps us (and I suspect you) interested. Exciting to see the wiring coming together. My 57 had a new stock loom put in and there was about 10 wires!

Had to pause at 4 mins 21 secs to say YOU, my dear, are an ABSOLUTE SMOKE SHOW!!! The reason I enjoy your channel/ content is because of your constant funny quips and definitely your skills and knowledge in things automotive. And the cherry on top is that YOU, my dear, are an ABSOLUTE SMOKE SHOW!!! Utmost respect to you, of course!

Everytime I see a harness I think "Little knot here, you can work on that". Your success with this car will be sweeeeeeeeeet.

Cudoos on plastic wrapping the exposed cylinder head. A true technician! I too did a S5 turbo RX7 swap into an 86 RX7 body and only two people online said it was possible and even the rotary performance shop in Dallas said it was impossible but haha persistence and wiring diagrams paid off!!!

It’s coming together. Making a new wiring harness is a bit of a daunting task. It’s easy to get confused about the various wires. You’re making it look easy.

Having wired up many after market ECU's I agree totally most of the screw ups occur when you take the wire color for granted. I always do and end to end map of the wiring it takes time but always saves in the end.

I've got a 1st gen-supercharged that I've needed to change the wheel bearings on for like 10 years now. Your motivation is inspiring, your 2nd gen is gorgeous.

Kudos to you for the level of detail you went into checking and modifying the body harness, so many youtubers just throw money at the problem, nice to see someone who knows what they are doing when it comes to wiring. Can't wait for the next instalment :)

Always informative and well filmed! Thanks Sarah!

You pour your heart into this stuff. The attention to detail will pay off!

Sarah, you’re doing an absolute stunning job! Screw all the scripted YTers and their hired videographer hands…. Keep staying as you’re, genuine and not scripted keeps the subscribers coming back!

WOW! I wish more car youtubers would go into the more technical parts of cars. We all learn a lot from it.

Excellent video, along with some impressive analytics of the wiring layout. Great job!

Nice. Gotta love that feeling of getting something accomplished. A lot of work, but hopefully it all goes smoothly and fires right up once the you get the new wiring all installed for the Link.

I gotta love your systematic approach for labeling wires and documenting everything. You are awesome!

I am amazed at the patience and thorough quality control you have in wiring. I wire in my detector and camera and really feel accomplished with my custom cable and routing. You are definitely dedicated.

Wow! Your methodical precision and attention to detail are impressive. Wiring is not an easy task, but you make it look that way. Awesome work, Sarah. Thanks for keeping your penguin friends in the video. Haven't seen them in the last couple of car reviews. Looking forward to seeing the finished product.

I fixed a lot of mechanical issues on the Porsche 928 S4 I resurrected. The only issues that were left were electrical (and timing belt). I tried to fix each electrical problem and failed. I sold her on to someone who thought they could fix her. My hat's off to you for your electrical genius. It's not as easy as you make it look. 👍

I am so proud of all you have accomplished. Cant wait to see it running. You give me imperasion to start my project. I am installing a Mega Squirt on my 82' 280ZX

You kick ass . I really appreciate how hard you work to show us all that you are working on. Thank you Sarah you are much appreciated and loved . 😆

"This is not an accredited class." I'm dead now.

Wiring is one of the most difficult tasks when completing any engine swap that wasn’t originally installed in the car. The videos of you going in depth on this serve as an awesome reminder that while swaps aren’t simple, it’s doable with methodical planning. This type of content sets you apart from all the other automotive RU-vidrs and I hope this generates the views, or more than you were hoping for. Keep killing it!

Wow. It's great watching you do this because you really know what you're doing !!

If I need any very detailed wiring done, I'm looking for you Sarah 🤣🤣. You are extremely patient and take educating yourself to a whole new level.

Sweet video Sarah.....You sure are on top of this whole re-wiring your harness thing for the MR2.....If any problems arise after it's all back together I think you will be one of a very few people that will know where to look to fix it.

Sarah everytime I watch you and you start doing wiring it amazes me the knowledge that you have on wiring I am a complete idiot when it comes to wiring you're amazing and you do not let it get to you obviously 5 hours proud of you you have way more patience than I do even if I had a schematic I don't think I would have the patience to do it very very nice job

I was thinking I would have hooked up the new ECU to the old harness and made sure it worked before ripping everything out and introducing numerous potential miswire faults in my fabrication process; then changed the body harness and made all those extensions. And truthfully I would have skipped the new harness and just troubleshooted the old one and added a new fuel pump resistor circuit and any others that tested with too much resistance or intermittent continuity when shaken. They spayed everything down in CRC 226 to restore electrical contacts and drive out the moisture. I can't imagine doing the work you just did on anything less than a pre war Bugatti. Which would of course be so much simpler. Alas, I lack your courage, patience and skills, to say nothing of your confidence. You are an inspiration to every DIY builder lacking the funds to pay someone else to get it done. I salute you. Love from, and beautiful weather in... NYC. Larry

This is incredible, your mind is perfect for this kind of work Sarah 👏

On today's episode Sarah loses her mind wiring and puts the penguin to sleep. Penguin commentary had me rolling. Sarah I admire your attention to detail.

Amazing how you are able to get so much done while filming and having a life at the same time. Cheers to that!

I am professing my love for the way you do things...with the exception of eating on camera. 🙃 Seriously, I have OCD, and there isn't one thing I'd change about how you do things. At times, I find myself taking a longer time doing things to do them the way I feel they were meant to be. So, to see you break things down and do them how you want to do is completely understandable/relatable. Thank you!

Hard work always takes a long time and tedious. You are always a pleasure to watch due to all your detailed hard work. Thank you.

SO many great lines in this video, hard to pick a favorite !

Neat and methodical your experience shows through. I used to push cars by myself my knees now sound like an old trucks leaf springs, my 1926 Oakland was the straw that broke the camels back.

I've said it before but I'm always so impressed with your attention to detail! I wish I had the patience for that.

great job drilling down on the wiring harness. once someone can figure that out, they can figure anything out and the possibilities for projects really open up

I always loved the MR2. There was one like yours in Hanover Pa. back in the 90`s. Turbo and all.

Your attention to detail is second to none. Just Wow!

Your Grandmother would be proud of you on sooo many levels. 👍

I love that you're electrical. It's a rare and precious thing.

You are amazing, so detailed and persistent. Keep it up.

Boom! This is why I tune in! I got two MR2s and am still learning from you!

7:35 Me: looks for the straight edge and ruler Sarah used to get her script and righting so straight on the board.

Excellent logical thinking and organization here. Kudos!

So much excite.. can't wait to see how this comes out!

Happy Monday Sarah!!! Earlier than 72hrs, great surprise!! Stay excellent!!😎

You have done a great job on the wire harness!!

Wiring makes my head explode. You are amazing.

Kudos to your tenacity. 👍

about 13 years ago, i had a cressida i was doing a 1JZ swap, that already had a 2JZ swap with a butchered harness. after many endless days and nights of redoing the harness, I never got it to run. I ran out of money (I was in college) before I could getting it running. So many what ifs but nice job doing things right. fast forward to today and I got another project car sitting in the garage, I don't plan on giving on on this one though.

I'm like you in I have to understand something to work on it, I am doing the same thing on my Jetta to swap from OBD1 to OBD2. Some may not need to get it all laid out and labeled. But I did for it to work in my head, and if I can make it work in my head it will work. Ty, I'm not alone.

Sarah , you are so Patient and persistent and I applaud you for that . 🤗👍 That is something I do not have , patience and persistence .

Respect for tackling a job like this on your own. Spending all that time on research & doing things right isn’t fun, but the satisfaction of driving the car after all that work definitely is

A true professional. Love the detail oriented approach to the wiring. Caution: It's not all shaved back there.

The high degree of detail in your explanations is why I see your videos Sarah. Most youtubers cut a lot of corners in their projects regarding electronics particularly. You don't. Maybe it takes more time to see some progress, but I don't care, I'm curious. I prefer to learn something useful in the process. Keep it up, it's what makes you different. Great stuff.

Killing it Sarah. Keep up the great content.

This was a great video! I liked your method of going at this!

I am glad it is you and not me doing this work. Tip o' the hat to ya!🎩😀

I'm amazed that so many have taken note of your hand writing (printing). Most thought your dry board skills were most notable, but I first noticed it when you were taking notes on a note pad. That aside wonder video.

That was super impressive.... great work Sarah!

Dos loves it when you service him Sarah.

Wow Sarah, you are truly dedicated to the most difficult jobs. I applaud you.

Mad respect on tracking these electrical problems down 🔥

Quality work young lady. You should be proud of yourself.

I can learn and laugh at the same time, it's great.

My 68 spitfire had a cross circuit between the brake lights and the ignition. If it was raining you could remove the key and the engine would continue running as long as your foot was on the brake pedal. Since the parking brake was rusted solid, parking on a hill was a balance of letting it roll till it died then brake and put it in gear. Got to love a car with only three fuses.

Excellent job😉 knew you would get there in the end 👌

Dedication! Wiring harness done!

Nice work Sarah!

Excellent video Sarah!

You are such a talent in so many ways!

It's coming along! Regards Nico.

Love that Tech Data you created on the white board!

Great job, I laughed at your EA1 joke.

"it's not going to be entirely shaved back there, i'm going to leave stuff that serves a purpose but also make it look clean" you mean like a landing strip or something? LOL thx Sarah, that one's make my day

What an outstanding communicator you are ! Some big company will make you offer soon...

I love your humor, we would totally get along. Not sure if we would get all that much done, but it would be fun.

Just try and determine how much troubleshooting time and frustration you avoided with that 5 hours of detailed documentation. This is a great video. So many laugh out loud moments. My fav? The cardboard box opening at the beginning. That was so true!!! Side note - in New Zealand we are entering winter and it is 3deg C outside at the moment. It is weird watching our Northern Hemisphere brothers and sisters get hotter and start wearing T shirts and shorts, and complain about the heat. Looked so nice that evening in town.

Always eye candy, never a bad day !!

I love when you say "body harness." I feel your passion.

as an electronics expert. everything you say and are doing makes perfect sense to me. when you turn this up there will be no smoke.
