I used a f/w bushing. Im running 1/0 down the drivers side, you cant tell its there. There are other ways to do it, this is just what works best for me.


Dont forget the pics/ vids when you're done!

that is what i did and the only thing i would recommend to do!!!! no matter what size wire you run. if you use a compression connector you will no chance of any water getting inside. if you just run it thru the factory wiring harness it will not be water tight. but to each is own and it you truck but for the extra 10 min of work and $10 do it right the first time

Where do you get a f/w bushing like that? Would that work for multiple wires as well, or only be water tight with one wire running through it?

I am looking to go through the firewall as well, but want to do it right :thumbsup:

Thanks!

I'm assuming you had to drill the hole for that "f/w bushing". Is that a correct assumption?

check ebay out for Stinger firewall grommet. I get my Stinger stuff from seller "bag-boy" Awesome price, shipping and customer service.

HERE

I used Stinger 0 gauge through one and ran it down the driver side under the trim. It was a tight fit but I got it. I also went throught the floor and up the inside of the rear fender flare.

and pictures...
There's a little rubber door right above the factory firewall grommet

I removed it and some of the foam insulation and drilled the hole with a holesaw


Here's were mine landed and I couldn't be happier. It's high up enough to be able to easily bend it to where I need it.



Here's where I ran the 0 gauge


and here's wher it went up into. It lands right behind the storage door on driver side rear wall.


I'm eventually gonna add a fused distribution block in that compartment so it worked out great

Speaking of power wire... How did you connect your power wire to your battery? Also Thos of you with the Big 3 done How did you get all that 0awg connected to the terminals. I see Bag Boy has lots of Terminals but i don't know which style i want. sorry if this is :eek:fftopic: im really not sure. if it is i can start a new thread.

The best and safest way to run power is through the firewall, especially if you're installing a large gauge or something that will draw lots of amps. I wouldn't hook something that large to the rear power center. Remember to protect your circuit (fuse, circuit breaker) near the battery.

LMMJ does your power wire acctually go outside of the car? or is that still inside. and i define outside as, could it get wet in rain? could you touch it without entering the car?
It's only "outside" in the engine compartment. I have it ran right behind the fender flare but still in the truck. In that pic I posted, to the left is the fender flare/door and to the right is the panel that the interior trim mounts to. I went this way cause I couldn't get the wire ran by the back seat without bulging the carpet.
