I just attempted to install my new head unit, but the wiring harness that I bought was one wire short. I read that if you don't buy the expensive adapter that this would be a problem but you could wire the red wire from the head unit directly into the fuse box to a key controlled fuse... can anybody explain to me the easiest way to do this?
Yep. Buy some extra wire. Connect extra wire to red wire on hu (or the accessory wire), then run that wire to your fuse panel, specifically to the fuse that is for the radio. connect wire to that fuse. I still don't recommend people do that tho, there is a fuse there for a reason and jumping stuff like that can cause shorts and fires.
The extra wire is the red wire from the head unit.
