What do the 4 Wires of a Prodigy Brake Controller Wire to on a 2010 Toyota Tundra

Question:

I have a Prodigy # 0001037767 installed on my 2010 Tundraafter removing the panel below my steering wheel to gain access to the fuse block, I got the lights stated aboveABS, Traction and 4HI-after learning all the lights are coming from the ABS system not communicating, I looked back behind my panel and found a small green wire coming from J29 plug dangling. It appeared to be very close to one of the other wires coming from the Prodigy controller so I am thinking it may connect to one of the controllers wiresit appears this controller was hard wired into the Tundra as each wire is wire-nutted to a wire on the tundra-can you help me with a diagram and instructions about how to wire the unit to my truck so I can troubleshoot what wire goes where??? Any help would be greatly appreciatedI am sending a picture showing the green wire in questiontx

I attached a picture that shows what circuits the wires of your Prodigy brake controller will connect to.

The blue wire is the brake output circuit which carries the brake signal to the brakes, the red wire is the brake switch circuit that will have voltage when the brakes are applied, the black wire is the 12 volt power source which powers the controller, and the white wire is the ground circuit.

The green wire you found will not attach to the brake controller. You could use a circuit tester like our part # 3808 to determine if and when it carries any voltage to determine the function of it.

It sounds like an ABS wire is not making contact somewhere on the circuit. All I can really recommend is that you go over for the wiring near the wheels and work your way up to try to find the problem.
