Cheapest LS swap harness in the world! Factory quality! Same wires GM uses! 

You should put out a manual or how to for us guys who can't afford the EXPENSIVE stuff I would definitely buy one THANKS FOR YOUR HELP

JR great video, I’m using your pointers. 👍

I'm sure the wire shops hate you but let him hate you for educating us

THANKS to you JR, we fired up our first junk yard rebuild yesterday! Your “straight to the point” videos are some of the best. We have real jobs and no sponsors, so budget mined swap was the path we took. Keep up the GREAT WORK! Ordering some of your swag and sending beer $$

Exactly how I did the swap in my 1ton obs!! Bought the truck on Wednesday and on Saturday I was driving it!! People over think this part of the swap. Great vid as always!! Thx for spreading the LS knowledge!!!

Just want to say thank you for all the info you provide in all of your ls swap videos you have convinced me its time to do my first ls swap lol

Oh my GOD!!! You are so funny!!! In the rear bumper. Yea I know people that are like that. I thank you. You have made this so simple and will have saved me sooooo much money. I was lookin at the Fueltech FT600 for my 03 crown Vic LS swap and yea I don't need to spend the $2400 bucks for the Puter and another $1800 for the dedicated wiring harness. I just wanna do burnouts and go get ice cream. I don't mind buying tires. I work at the Goodyear tire plant. I get a discount. I'm not doing No Prep racing or any of that stuff. I'm not tuning my car for every time I get in it..... I just wanna drive my beater and have fun. I'm gonna try to get a 6.0L to swap so I can get the most power out of it without the rough lobing. I like a smooth idle. And if it doesn't do a nice burnout then I can watch another turbo video from you. I thank you very much. You have opened my eyes to the dumb sh*t out there that they tell you you need and you don't.

Thank u sir I appreciate u so much just hope I can figure it out also

Man I wish I seen this video a month ago.i was watching some other B's an I have half of the wires pulled out of c3 c1 .so now I'm going to do what you said.then try to put back all those wires I pull out...ty.love your video

Eleventy million dollars with the fuse block in the rear bumper! 😂😂 Great stuff, love the info and your sense of humor, lol

I have the second fuse block.my question.do I cut all other wires off or just leave them in..

I'm having a issue... maybe you can help... I am not getting power to my transmission solenoids. I watched the video,but there is NO wire in the f-2 position... and b-9 has a pink wire in the stock location.. any thoughts or help is appreciated

Would this method work on a swap into a non GM vehicle? I’m swapping a bmw e46 cheers man thanks for your help!

"Eleventy billion dollars on your LS swap" should be a tshirt slogan. If buy it in a heart beat😅😇

What do you do when you upgrade the motor? Like a bigger cam, how do you tune it?

JR how you doing? Been a few days since last video. Hope all is well. Quick question: we changed tune to run one fan, but which pin will send signal for relay ? Or should just wire up both pins? ‘03 harness P59

Question so if I pull everything out of a 99 chevy Truck with 5.3 .Do I still have to have the computer tuned? I want to put in a 80 camaro.

Need help swapping lq9 in 99 tahoe

I like your logical thinking

What would be involved in retaining the OBD2 port? My system will require an OBD2 port to plug in my BIM dakota gauges.

Thanks for another down to earth informative video...saving this one for future reference.

Thanks for the information I am about to do my first ls swap into my wife’s 84 k10

Pretty work! Thanks!!!!

You sir, are a fucking hero.. Many thanks 🙏🏾

I guess I'm still confused. So if you do the wiring harness like this it will start up and run? No sending the ECU off for programing? Also I have a gen 4 ly6 I'm trying to accomplish this with.

I had just said when you add up if you are buying a harness then the holly starts looking compelling because you also get a wide band for tuneing if you are going to do a cam or anything other than just the swap I mean I already have HP tuners and can do everything with a stock harness but I remember you got a harness from alibaba why did you do that

Is the bcm necessary for trans gear engagement on an 03 escalade awd setup? My setup just doesn't seem to want to go into any gear.

Thanks I was really wondering about some of them things.

Hey what’s the guys name that does the torque converters? Ryan jans? Is that how it is spelled? I need a higher stall low budget torque Converter for a 4l80.. just let me know.. thanks

Could u make me a stand alone harness.i can't do it..I'll buy it....

I like an Idiot didnt grab the fuse box, so what now, I guess I could go to the wrecking yard what would you think?? Or I could order 1 online

So if you do this you don't have to reflash pcm?

allready got a '99 2500 GMC doing nothing in my yard so built me a harness for my C-10 swap cost me 0$ with help of LT1.com was easy to do :o)

I thinned down my harness for my '91 caprice swap and not going to lie, I wish I hadnt. This would have been way easier

Thankx JR! 👍🏁

Will harness from a 5.3 work with a 6.0? Both O2 models.

To bad we have to many assholes cutting all the wires with a sawsall and dont care what other people need. First thing to go under the hood is the wire harness gets cut to pieces. That should be made a big no no in every junkyard.

Unless it’s drive by wire then grab tac module and gas pedal. But not much more to do than that.

Thanks JR

Do the vats still have to be deleted?

You’re the Man !!!

Thanks for this video. I know it was mostly focused on the harness, but 1 question... Will this make it run without programming VATS out of the PCM? I had the whole donor vehicle that already had the 30 minute security relearn/bypass done with the two wires from the Passlock sensor twisted together, so i snagged the BCM, hooked up the BCM powers and grounds, 2 wires to the passlock sensor still twisted together and the Yellow security wire going the PCM. It runs laying on the ground, no flashing PCM. Just wondering if I can make it run without the BCM (just to free up some more wiring) and no PCM/VATS programming.

Would this work without turning off the VATS?

Great info about to pick up my 2004 Rainier 5.3 2wd donor

I have a few ?

This was how I did my first swap hole vehicle now im on my 2nd swap and I didnt realize the harness was cut its missing the 02 sensors for passenger side and maf and there's some other wires in there that think were coolant level and something else im having a hard time figuring out which wires go to each sensor there 2 purple 2 tan 3 pinks the purple and tans go to each 02 not sure how to tell which is upper and lower the 3 pinks go to each o2 and maf same thing on those not sure which goes were

how do you bypass the VAT?

Thanks again, your a good person

? What about tcc ?

Ya, but im LS swapping into an 03 dodge ram. Just to be difficult. :(

Great info.

Damn I wish I would have done this rather then my harness thin down, could have got one with electric fan relays built in too!

Will this work for 4.3 5 speed to 6.0 t-56? 2005 single Silverado?

Wow, best video ever!

I do custom harness for 350.00 water proff fuse block

Friggin A bubba........ its a runner not a Foose build!

Eleventybillion. Stealing that.

Right on

Let's see what's new...

I love using the little fuse blocks from amazon for wiring like this or get fancy and get the all in one blue seas one that does power ground and switched in one package. I love a nice neat and labeled wire distribution system

11billion dollars🤣🤣

👍
