Where can i feed some 18 guage wire through the firewall on my 87' base model camaro?

thanx

 

If you can't feed it through with some existing wires you may have to drill your own hole. Wherever is convenient and doesn't hit anything on the other side and where you can easily find the wire when it's pushed throughl. It's a good idea to use a grommet. Maybe close to where existing wires go through.

 

behind the master cylinder is a large grommet you can use.

 

Under the column is the cruise mini-harness grommet with lots of room. On the pass side you can feed a small handful through the antennae grommet

Whatever you do be sure to insulate the wires where they pass through steel with at bare minimum a rubber grommet
