    I am in the process of getting my LED light bars all finished up. I finally mounted my last one today. While I was there I figured why not take it all the way and get the job finished up. Well wouldn't you know it the hardest part was finding a good place to run wiring through the firewall. Has anyone done it without screwing everything up and making a mess? I tried running through a very small opening right behind the brake booster but there was too much crap in the way.

    I did a quick test light of my setup and damn it looks good :D

    just use some electrical tape and connect the wire and the tape to the end of a metal hanger and push it through that grommet with all the wiring you are talking about..I've ran a number of wires through there with no problem.

    I found a pretty easy way. I ran a bunch of wires for my LEDS and shit thru the opening in the boot on the firewall. I put a flashlight in the engine bay pointing at the hole then went inside and ran the wires thru where the light was coming thru. It's real easy.

    I have pics but can't find them all of a sudden. I thought I had them in my LED thread :confused:

    On my 2011 V6 DC there is a drain tube on the passenger side that passes through the firewall. You can remove the tube, run your wires, then reinsert the tube.

    I used an existing gromet behind the brake booster and ran wires through some corrugated tubing I stuffed in there.

    Comes in right next to the steering column.

    I was able to run a few wires through the main harness boot behind the e brake by staggering each wire and taping them to a hanger, but instead of punching a new hole, I folds the tip of the wire over the give It a dull end, and putting a fine layer of grease on the tip, and on the tape.
    The grease made a huge difference on how easily the wire would follow the existing wires through the boots.
