The directions say to tap the "Red wire" for the signal to the controller.
There is no red wire at the brake light switch.
The wiring diagram in chiltons shows a white or white and tan wire.
I have tapped the white wire and the brake controller lights up all the LED's as soon as I do that.
Did I screw up?
The controller is from NAPA.
It is labeled 'TAP'.
There is a Black (Power), White (Ground), Blue (Brakes) and red (Brake light switch)
