Mine is installed on the left side of the fire wall, in the area where the master cylinder is. I didnt install it myself, was installed at a retail establishment. Works fine.

Was there a hole there before?
Or do you think they made one?
Thanks

Found it!



IT was easy for me because I had already removed the AC blower and AC Evaporator. But I would imagine it might be hard if those were in there?

Where is that exactly? whats in that picture? The black things are brake lines right? Right now, I have two power wires and a tach wire coming underneath the engine bay and into the cabin from underneath the driver's seat. I hate it. It looks really unclean, and I'm woried someone could cut the wire to my alarm. I want to run it through the firewall instead and into the cabin underneath the steering wheel.

Looks like I'll have to drill a hole, and since so many people have asked about it, I'll post pics when I do it.

Suneet the pic he posted is on the right hand side of the car near the high pressure side of the A/C. You can see the valve in the pic. Mine was done the same way, just on the opposite side of the car near the master cylinder. Just takes a little effort to squeeze the wire through.

Will it fit 2 0/1ga wires?

Right hand side of the car is ambiguous Is that the passenger's side? And you'rs was done near the master cylinder, which is driver's side.. did you have to drill a hole or you squeezed it in somewhere?

Yes, big guy, the passenger side of the car is where his pic is showing. Mine was also squeezed into an existing opening just the same as what was shown above. I am running a 2 guage wire for my install. My amp and sub was installed by Circuit City and I had them tap into the stock radio (for now), If you can find an access area, use a flat head screwdriver to pry the opening up so you can squeeze the wire through the opening.

This is on the passenger side. It runs with with the ECU wires. It was easy for me because I was uninstalling the AC blower an AC evaporator. (found under the glove box.

i drilled a hole on the driver s LHD side firewall right in the middle of the only open space you can see there. you just have to make sure there are no wires/lines/anything on the other side before youstart drilling.
