7 pin no power to trailer brakes
I'm trying to install a Prodigy wireless brake controller. There is no power to the electric brake 7 pin. The pin is in the 5 o'clock position. Blue wire runs to it. I'm having trouble tracing it. Fuses for brake lights, turn signal etc. up front above generator. I can find one for the trailer brakes. Where do I go from here?
