Where would be the biggest hole that i could use to put a wire through my firewall? I'm installing my underglow and if possible i would want to put it through the fire wall, but as of right now i can't find anything big enough, the plug is about an inch wide, but only a quarter inch if that thick.

 

there is a large rubber grommet that your main harness goes through. you can use that. lay on your back on the floor under the driver side dash with a flashlight and you'll see it up there.

 

there are wire grommet paths on both sides of the fire wall,just untape the ends and get a coat hanger and push it through to a person on the other side,then tape wire on to it and feed it through,once in place retape the grommet and good to go.

 

I used the one behind the glovebox. you can unscrew the ecu box and you can access it very very easy. A lot easier than the driver's side one. I used a small knife to poke a small hole and pushed it throw. If I can do it, you can do it for sure...cause i had know idea how to do it at first until i decided just to go for it. plus mine is a 4 guage wire

 

i'll be able to fit an inch wide wire end through those though? i just want to make sure before i start doing all that and then not be able to

 

inch wide? use the grommet unger dash on drivers side, tape it to a coat hanger and push it through

 

ok thank! is it easy to get through from the other side in the engine bay?

 

yes, it will come out somewhere behind your throttle body if you use the one on the drivers side.

 

awesome, now i just have to wait untili tuesday before i can do anything with my car again ><
