The boost valve assembly (valve uint) cable plugs directtly into the harness (valve unit harness) that plugs right into the back of the controller , and the other harness (power harness) plugs into the back of the controller (red 12v+ / black ground-) The only other harness is the speed limter cut harness that is usually sold seperate which is white and black wires (page 12 on instructions) You don't need this if you don't want.


Plug in the harness, put power and ground, vacuum line, and you should be good. I have on my Ty and it was simple. I think you have an "extra" you don't need.
