So I'm trying to put in 7-pin trailer wiring, which requires me to get a wire through the firewall for the brake controller. I've done some searching on how to get through the firewall, and it seems the popular solution is to go through a port above the accelerator that I guess is only used for a clutch component (so I've gathered from other threads). However, mine appears to be in use (being an M/T, I have a clutch), so that looks like a no-go.
Has anyone found a good way through the firewall on an M/T model, especially for '09-'10? I did see a rubber grommet way up high and center on the engine side that appears to not be in use, but I can't locate it on the cab side and it looks like it might be behind the radio. I'd really like to avoid taking out the radio if possible.
Also, is this something that I might have to drill a new hole, or is that a really bad idea?
Thanks a bunch in advance!
