I'm installing aftermarket foglights and I can't figure out how to get the wires thru the firewall to the switch. The two holes i found are for the existing wiring in the car, but I can't get the wires thru the rubber. Is there another way around????

use a knife to cut a little slit in the boot that covers the factory wiring harness. Then tape your wire to a long screwdriver and push it throgh to the other side.

 

Use a wire coat hanger instead. Much easier to fish wires through that boot.

 

^agreed on the coat hangar. you can pass it thru the grommet by making a slit in it/w a knife, just keep it a little smaller than you need; rubber stretches
