Drawtite Brake Controler


New Member
I was given a Drawtite Activator II the other day, it came out of a repossesed truck and is nearly new. However, the wire's were cut near the back of the unit and I have no idea how this thing wires up. There are four wires coming out of it, red, black blue and white. I'm assuming the red and Black are pos & neg, but not sure of the other two, but imagine one is for input (from brake light switch?) and the other output to the trailer harness (or something like that)

Anyone know exactly how to wire this thing up?
