I am running 4 AWG power wire to my amp and I can't find an existing hole in the firewall..... is there a good place to drill into or does anybody know where there is an existing hole at? Right now I just ran it through my door jamb and it looks like crap and the door is gonna cut into my wire!!! Please help....thanks Sean Lucas
There is a large hole in the fire-wall to the left of your brake master cyclinder. It is in between your master cyclinder and the shock tower. This is the hole that is in place on all W-body cars for the clutch slave cyclinder mount... 8)
if you can't find the clutch slave hole then there is another where the heater core pipes come into the engine bay.
On the W-body cars it should be on the drivers side of the car in between where the brake master is mounted to the fire-wall and the drivers side shock tower. It is buried and has a rubber grommet plug in the hole... 8)
