    Routing wires through the firewall doesn't have to be that hard. Depending on what your trying to route, you could piggyback the wires along the wiring harness and not have to do much of anything, if they're small wires.

I'm not that familiar with where the locations are at so it would be a good idea to search the forum, or start your own thread.
