firewall

[Disturbe240]

i have a 1990 skyline gtr im trying to install a boost controller and other gauges, but i cant seem to find a hole in the firewall to pass the wiring through it. is there a hole to pass the wiring through?

just follow wires that go into your fire wall and use that hole

On the passenger side, just behind the strut tower, you should see a group of wires that go down into the fender. There is like a foam piece that holds it in place/seals up the hole. Move that out of the way and you can see where it goes from there.

If you can move some of the plastic on the inner fender well, you can see where it goes in between the fender and the unibody. That line then goes into a hole that is located just above and behind the ECU. If you unbolt the ECU, you can kinda get to it.

I did that for my boost controller on my Laurel, and they are pretty much the same car as the R32.
