I don't think the Jordan uses the brake sense wire. That wire normally supplies voltage to the controller when the brake pedal is depressed. Most electronic controllers, like the Prodigy, use this wire. The Jordan uses a cable connected to the brake pedal to sense when and how much the pedal is depressed.
I do not have a Jordan but I was considering one and studied them a little but decided on the BrakeSmart. Looking at the picture of the Jordan, it appears to have only 3 wires to hook up. The blue one goes to the trailer brake, and I am pretty sure the red and white are 12V and ground.
Again, I am not an expert on the Jordan and maybe someone who has one will respond, but I think I am correct.
