This might be a really easy question, but what's the best way to route wiring for a switch from the engine compartment to the cab on a 2005 tacoma? I'm installing a set of KC driving lights, and want to route the wires through the firewall. I have found the existing place where the factory wires go through, and that looks like the best option. It seems like the easiest way would be to cut through the rubber there and run the wires through it. I want to know what has worked for other people before I go ahead with it.
