Trailer Tow Hack
I wanted to use the trailer tow odometer when towing my boat. But it didn’t work because my trailer has a 4-pin connecter and surge brakes. So, I decided to trick my truck to make it think electric brakes are connected so I could use all of the features of having a 7-pin trailer hooked up...- Bufordw
