I need help finding a hole in the firewall to run some wires through. I have been looking and I just can't find any. I have a 85 camaro base model with the 2.8 mpfi. I am looking to run my fan wires and my fog light wires. so if anyone could help I would be extremely greatful. Cause I really don't want to have to drill any holes in it.

 

Here are a couple of suggestions.
Route the wires through the grommet that the ecm harness goes through. It is under the blower motor.
Route them into the back part of the passenger fender well and go through the antennae cable grommet.(kind of a PITA).
Or route the wire down along side the trans and up through the shifter hole. (works with a manual only).

Good luck

 

Your best bet is to run them through the connector on the driver side by the brake booster. The ECM connector on the passenger side is filled with what amounts to hot melt glue. The one on the driver side is just sealed with a thick black putty and is easily cleared out of the empty holes with a heavy guage wire. This connector is just above the heater outlet by the driver's left foot. I have run several wires through there with complete success.

 

thanks I found the hole you were talking about and I pulled the stuff out thanks alot for the help.
