Im having issues with trailer brakes. 2003 LC - I have OEM trailer brake harness under the dash running to my tekonsha brake controller, hardwired 7 pin trailer plug to the OEM trailer plug by the spare tire. I have all lights working - left/right turn signal, brake lights, running lights, reverse but I have no trailer brakes.
I verified brake output at the trailer brake controller up front but I can't get brake signal on blue wire at the rear.
Does the blue brake output wire run directly to the harness at the spare tire or does it branch off? Is there a diagram that'll show where the wire goes. Im tempted just to run a separate blue from front to back.
