Places to route wiring in through firewall?

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

 

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

 

i did the same thing!

 

Heres my pics........kinda get the idea.

 

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.

 

Here are pics:

 

Thanks fir the tips guys! Now I just gotta find the time to do it and find a hanger! Lol

 

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.

 

I got it guys, thank you so much for all your help!

 

I just installed my antenna through this hole. Worked like a charm!
