How To Run Wire Through A Firewall, Not A Doorjamb 

That tool! This video is worth it just for knowing that tool exists! When I think of all the times I could of used one...

I haven't seen someone run a power wire through the door jamb before...was thinking about doing it too! Thank you for the video.

You are the man bro 😍 no more wire-through-the-door-jamb for this guy 💪

You're fighting the good fight Ed; keep it up.

Thanks a bunch. Needed to run a temp battery wire for my tow hitch wiring and thought my only option was to run undercarriage but now I have options.

The door lock as the ground got me😂

Awesome video! I don’t know how many times I’ve had a car in the shop and seen the same thing.

Haha this video took me back to my teen years ,loved it 👍

I was looking for a way to reroute a vacuum line and this helps me out a lot as well as future reference for some extras I may be looking at next.

This was a very well made and helpful video, thanks!

As much as I love that you are showing how to do things the right way, I feel that if you can use the wire poke jobby you can use a uni bit and make your own hole and use a dedicated grommet, that way if something does melt it's not welding your ecm harness....just easier to stay out of trouble then to get out of trouble 😉✌️....and I do have mad respect for what you do, don't let my opinion stop your viewers from doing what you show, I have seen thousands of " self installed" items as a mechanic for twenty plus years and I've seen what happens when full batt amperage is applied to all of the crkts at the same time going through a bulk head ....💥💨♨️⚡🔥🔥🚒

Wow..I have learned a lesson....I am cb radio hobbyist and I use to run the wire through the door jam..lol...now I know what to do now

Guilty of the door jam run... I didn't want to do that for my wife's car. Thanks for the video. I'm doing it right this time! I'll fix my truck in spring when it's warmer out.

Lol I laughed damn near the whole video. Good knowledge to share. Thanks.

Thank for showing the wire grommet tool!!!

Good video, I'm trying to install power wires for a mobile ham radio through the firewall. Problem is the harness comes with two huge fuse holders and might have to make the hole larger than what I thought was practical.

Great video and the door latch as the ground was to funny 🤣😂

Love the introduction 😂

Subscribed for the ground wire wrapped around the door anchor

You and I have the same pet peeve’s for the “I know it all crew” 😂🤣😂😂😂

Very informative .. I am doing a power wire install for my mobile ham radio. Never heard of or seen a Grommet tool. Your video just have me Hope. No lol. Very cool indeed.

grommit tool...why haven't I heard of this before? That's awesome!

Great video bro!

So informative. Thank you!.

Went on Amazon and bought this piercing tool with the quickness!

What a cool tool. Never seen one,,,its a "must have" now that I seen it !! Lol. TY Bro ! Great video ! 😎✌️

Really did like the video 🤘🇬🇧from England !

Love this video very helpful 👍

I also, like HifiVega, had no idea that there was such a tool as the "grommet tool"...I like it, and I like this vid...AND, the guy who made it! Z-BOP!

funny + informative video, keep up the nice job.

Thank you for this video I never knew that gromit tool existed I just purchased one.

That's awesome.. you are so genius and funny 😁. Thank you sir a lot. Wishing all the best to you.!

Nice tool !!! Thanks

Thank you!! This was so useful!

Amazing! Keep it up!

Thanks for this! This helped a lot! Didn’t know the tool existed.

LMAO that ground to the door latch wow. great video, thank you

Thank you for the tutorial. I plan on doing this for a La Cucaracha horn lol

Ty! Took me an hr to give in and look on youtube for some help 😅🤦🏼‍♂️

Thanks for this! Very useful

Thank you for the video!

LOL!!! Great vid man.

This is a great video!

Me being new to this is it bad to puncture the wire wall but I like that I don't have to drill any holes to run wiring like I have seen in other videos

I didn't it in the door jam of my Altima but I put it through this little hole behind the panel and behind the hinge. It was really tight and never got snagged. Also you need fuse at the batter to avoid it catching fire in the case of a short

thank you for this video

Looking to install a space heater into my car and want to run wires from my battery inside.. this video saved me as I didn't have any idea how to get wires in there. Now I do

This video is under-rated AF xD I love this AND I finally realized how to get into the firewall grommet. I was prepared to pull the shit out (installing driving lights)

I thought BigD was gonna roll up for a second xD

Thanks!!!!!!!!! I didn't know that tool existed.

Getting ready to do my first install. I’m so glad I a found this because I sure was going to do the door jamb method! Such a great video!

Very helpful

Pa plates, bro! You get the like! Nicely done! 👍🏻

through a grommet is always the preferred way but starting in about the early 2000's year by year it seems harder and harder to find a grommet that is actually accessible on both sides of the firewall and there are some cars like Audi's that you can't even find a spot on the firewall to access for installing your own grommet....

kool tool.

im installing a whole ass 3 sub 4 mids 2 amps sound system TOMORROW and it'll be the first time i do the job on a modern car(2017) and i came here in panic mode because during a quick inspection i couldnt find any single hole in the firewall which my 1992 truck has plenty of to make it super easy. i'll be working without that grommet tool, but man that thing looks handy to be able to put the wire through like that. i need to find space for a run of 4 gauge and 8 gauge, hopefully not too difficult

Nice shiv!

Great! Love your style! loll

I used MASSIVE AUDIO BT HEADPHONES and the bass came thrue clean & boomin but i got dog barks all 5.1 from the background sounds....lol but this was very good editorial!

Man...I forgot all about that tool. Haven't seen one of those in a long time.

HaHaHA. Looking for just this kind of info. Dude, too funny but informative. Thanks

Great grommet tool. never thot it out,,I will make one out tubing etc ,

Can we attach parallel front camera wire to fog lights so that no extra switch needed ?

Never even knew such a tool existed lol I always used the small slit with a razor blade on each side and some fish tape... And don’t you dare shame me for grounding my amp to the trunk latch in a future video 😂😂

good video

#1 pet peeve 🙁😧🙁😧 🔥🔥🔥

Thats how I had my sound system back when I was 18 till one day I almost catch on fire 🤦‍♂️🤦‍♂️

Excellent!!! Didnt know they made a tool like that! Thanks :-)

Thanks!

Thanks - great idea - looks like that grummet puncher tool is a scredriver (hollow shaft) cut off at angle?

How would you go about running wires from the cab back to the trunk? I’m installing a trailer brake controller

Dude thank you so much,

Love the video. I bought the same tool and got my 4 gauge wire through. Although I'm worried about water getting inside the cabin through the firewall when it rains. Is that something to watch out for? Should I try and tape up the grommet or silicone spray it?

Nice video. Knew that was PA!

Do u know wheres the grommet firewalll for the 2002 kia optima?

What's the grommet tool you used?? It looks like the punch that comes with the kits. But can't find just the punch.

I remember some kids in HS would "install" a stereo, and they would not hide any wires at all. Car-b-cue anyone?

Running 0 awg is such a pain getting through stock rubber grommets. Almost always have to find a good safe place in the firewall to drill and install a new grommet.

So it has to go from small gauge wire to a what size gauge wire? Is this mandatory?

What’s the instrumental you was playing in the beginning??🔥

That's funny, I ran my power wire like that for my first install. But at least it was fused at the battery.

Where would be a good spot to feed the power cable on my 09 civic ?

Wasn’t ready for the scion 😂😂😂

Can that tool work with 0awg?

The intro though 🤣

My first car had the wire in the door jam. It worked fine but ever since my second car in 2017, I've always cut a hole in the main boot that feeds the fat wiring harness through the firewall.

I once had a custumer pulled in with the Amp mounted in the Engine Conpartment!, lol. Hey, how was your Birthday?

I got a seat Leon mk 2 I need the wire to go through the wall anyone know where the grommet is Francis

What’s that tool u used

can you help me run the cables in a patriot jeep for a subwoofer please

That's hilarious. But when in a pinch you have to do what you need to do!! Lol

To YOU it sounds nice. To ME … it sounds like a drive-by approaching 😂😂

That amps ground location is crazy

1:34 is what i needed to know i think. I have the same big wire harness grommet next to the clutch pedal on the inside. But in the engine compartment that part of the firewall is hidden by the fusebox. So i have to unbolt the fusebox, hopefully i can see the other side of this grommet then 😀

Where did you get the grommet tool?

Idk the poke thiggy exist🤣 ive been using old hollow spatula handle to poke the rubber gromet..lol

Hi, I need some help, trying to do this except my firewall doesn’t have any rubber grommets, it’s this plastic material, any advice)

Booii u helped my ass!! Lol i always just ran it through the doors rubber grommet and then up through the fender.. as i was always worried of poking into the grommets i have tryed finding spots to poke through/drill before, but shiet this way easier if i have a big gromet in around the same area

The only way with the tools that I do have that I could run my amp wire in my 2000 dodge grand caravan was behind the window wiper motor which does come through my door jam on the inside and his under the bottom trim.

Hey Ed, where did you get that tool? Or did you make it?
