07-08: Pass wire from hood to interior - my6thgen.org

harvey · 04-29-2015, 11:22 AM

Hi, is there a tutorial anywhere on how to pass wires from the hood area to the interior of the car? I would prefer if it doesnt include removing the wheel well. Thanks!

From where inside the car to where under the hood?

Drill into the firewall or go through the gourmet, but me when I ran 1/0 guage power wire I had to drill a new hole.

That works. I'd be really careful doing it though.

Just watch where you are drilling and get a grommet or I guess tape for the hole so you don't cut the wire on it.

Thanks for the replies. I put in some led lights in the front bumper and ran the wires into the hood.. I want to connect them to a switch that I will install neer the steering wheel. Can someone please describe to me where the best place to drill a hole would be, or where the grommt is? If possible please post pictures. Im a lil nervous about drilling as I dont want to ruin anything. Thanks for your help guys!!

The best place to drill a hole in the firewall is where there isn't anything else. Anytime you do DIY work like this you take a risk, but if you're patient, take your time, and do your homework you can reduce the risk of something going wrong.

A grommet is this thing. You insert it after drilling the hole so the sharp metal doesn't slice through the wire.

Do you have a friend who could help you maybe? If you're too nervous I wouldn't attempt it.

Thanks so much for the reply. I have done lots of electrical work in the past so im not really nervous about the job. Can you please tell me where to locate the grommets? Im having trouble finding them. Thanks alot!

Once you know what size hole you're going to drill you can pick one up from almost any hardware store.

Where is the the location of the grommet thats in the car?

There isn't one. You'll have to drill a hole in the firewall and add one.

harvey · 04-30-2015, 11:31 AM

Ok thanks ill try it out

harvey · 04-30-2015, 11:35 AM

Btw do you know which wire color is the drls and the blinkers? If I dont end up drilling maybe ill just tap them directly in the trunk. I noticed on the top right of the hood under a plastic cover a bunch of wires going into the car.. maybe ill just tap into those. Thanks so much!

That I don't know. I haven't messed around with the wiring in this car much.

What's your end goal here?

harvey · 04-30-2015, 04:05 PM

I installed drl led lights and I would prefer to power them with a switch.. otherwise ill just have them power up automatically with the ignition

If you want them on a switch I would drill into the firewall, add a grommet, and put the switch somewhere on the side of the media console. I wouldn't want to tap into the existing drl wiring without knowing exactly what's what and I don't have a wiring diagram for it.

You might be able to find one here by searching for it.

Hausch · 05-03-2015, 09:21 PM

Yeah, for the switch right next to where the heating steering wheel is there is a spot you could throw it

KatIsFast · 05-04-2015, 12:35 AM

I wish I had a heated steering wheel

Hey, you don't gotta rub it in lol.

Also I wasn't thinking of sticking the switch next to the steering wheel. My preference is always much lower. Closer to the floor board and out of sight. It's where I keep the silencer switch for my radar detector (when it's in the car).
