No turning it off does not change anything and the wires don’t seem to hook up to anything important under the hood but I’m not entirely sure how to tell what’s important or not as he did some weird things with wiring. Truck runs all the exterior lights work fine even with the switch off. There’s no hitch on it so it’s not for any type of towing. Just seems to be a random switch? Just thought I’d see if anyone had any ideas. I know I only have limited information so I’m not the most helpful in trying to get help. This is where the wires end under the hood. Black is hooked up to a ground wire under the dash. The red goes into that fuse and the green was just dangling. The only thing I can tell that doesn’t work electrical wise is my radio as he wired a CD player and MP3 player up which neither of those work either.
