Where did u all run ur amp power wires through the firewall? im thinking of running it below the bulk connector from the engine bay to the cab. seems easy access from inside the cab to drill and i can still get to it in the engine bay. i also seen the groumet for the throttle cable but id rather not put it through there.

 

All of my wires go through a grommet that's already in the firewall.

 

Move the fuse box and drill a hole right under there. Thats what I did, you can't see it when the fuse box is in either so its clean.

 

Unbolt the two highlighted bolts and move the fuse block out of the way.


Get yourself one of these


Check both sides for any wiring or anything you don't want to drill into and drill. Then add a grommet.


Tada!

 

ya thanx for the write up, i know how to drill a hole.

looks good so far, hopefully friday i can start installing all the **** in her truck.

 

look near the gas pedal seems to be where the prev owner ran mine

 

Sorry for trying to help, next time I won't

 

x2 no need to be an ******* that was farily decent detail on demand.

 

Why not use a grommet that is already there?

 

pretty much i did what Korey did...but i did two 1" holes with 3/4" holed grommets. i got alot of switches in the cab. lol. holes hidden below the engine bay fuse box.

 

Yeah I have 2 big holes too, I don't know what size they are.

 

i ran mine under the truck its 0gauge so threw the fw would have been tough, in the ext cab there is grommets in the rear under the carpet for water drainage i assume. its zip tied to the frame then up to the body.

 

I ran mine through with the hood release cable.

 

I used a hole saw & installed one of THESE bad boys.

It works great for my 1/0ga power wire, but I have another smaller grommet for my fog light relay wires.

 

A few years ago, I needed to route a power wire and a couple of alarm wires through the firewall. Holes were drilled above the factory bulkhead connector next to the brake booster and grommets installed. While I was at it, I added some extra holes/grommets in various sizes for future mods and plugged them with bolts. These have proven to be very useful over the past couple of years and I now have wires and a vac line running through all 5 of the holes.

To make room for the drill motor, the underhood electrical distribution box was temporarily unbolted and moved over. There is a large wire bundle on the interior side that may need to be repositioned out of harm's way while drilling.

 

i just went through an existing hole

 

I always cut a slit in the existing grommet under the steering shaft. Its the best way IMO... drilling extra holes in the firewall FTL.

 

Wires near a shaft that spins all the time? I'll take drilling holes in something that never moves over that any day.

 

im gunna go with the place i wanted which is where bob drilled his. i do like those firewall grouments...better than the regular round ones...i think i will even drill extra holes for other goodies :-D

 

Did the same thing. With a good sealed audio grommet, you'll be good and the install will look clean.

 

thats how the previous owner had mine, i guess he never went wheeling because the first time i did it came loose and fryed on the exhaust manifold, i just put a grommet in an existing hole under the gas pedal area. fit 4gauge perfectly.
