Has anyone found a good location to pass wires through the firewall? I'm installing a Methanol kit and can't seem to find anywhere to pass the power and MAP sensor wires through. I'm not too keen on drilling new holes, but I will if i must. I'm hoping someone with an aftermarket stereo or a nitrous kit has found a good spot.

Any suggestions, pictures would be great too.

Previously someone suggested that in the firewall on the passenger side there was a grommet adequately sized for passing additional wires through. I'll admit I didn't look that hard for it, but I was never able to find it.

There is a massive grommet on the driver's side where the main harness comes through behind the pedals. I use that for my wideband and other crap. It is a two piece so the side in the car pops out and makes it easier to get the wires through.

^^ Thats what I used for my shift light, I found the one on the passenger side (inside the car) but having it come out under the hood was damn near impossible.

Yep, right up there behind the brake pedal area, I used it for my wideband install as well.

I used it for an electronic boost gauge.

I had my buddy drill a new hole on the paqssenger side underneath the cowl behind the battery box, we routed a nitrous line and a power wire for an amp through it and tucked the wires underneath the carpet. Turned out very clean and youd never know it was there even if you sell the car.

This is when I did my sub and amp.
As you can see in the last picture I rammed the wire through the steering shaft rubber grommet. It took me about 30 min to get through the rubber grommet.
It was a pain in the ***.
