Does HBA-CAM Adapter Module for Hydrastar Electric Over Hydraulic Brake Actuators have 2 or 4 Wires

Question

Question:

There is a difference between the wiring instruction and illustration on the one hand and the image of the product. Please help me to resolve: The photo image of the product clearly shows only TWO wires, white and blue. The instructions and diagram show clearly FOUR wires. For my 2008 Chevrolet 2500 with ITBC and HydraStar 1600 which will it be?

The old version of the # HBA-CAM used 4 wires, but the product was updated awhile back and now uses only two wires as shown in the photo on the product description page. The white wire from the HBA-CAM would tap into the white ground wire and the blue wire from the HBA-CAM would tap into the blue brake output wire, as you can see in the photo I've provided. You must be looking at an older version of the installation instructions.

If it is a 1000 psi then it would be the Hydrastar for drum brakes. The newest one is #HBA-10 and it has different wire colors, see picture. So you know that black is 12 volt power in and white is the ground. Blue/white goes to the break away switch.…

It sounds like you are speaking of the wires for the brake magnets. If this is correct, you will need to connect one of the wires to the brake controller output wire on your trailer connector and the other wire will need to be grounded to a clean…
