Older Generation Primus Cequent Brake Controller User Manual

Question

Question:

I just bought a 2008 GMC Serria 1500 and it has a Primus Cequent brake controller in it. This is not the Primus controller with a boost setting button on top but it has a flipper switch on the right side. Where can I find a user manual for it or how does it work for setting the booster? All I can find is the user manual for the one with the boost button on the top side. Any help is appreciated.

I was able to find the older style Primus Brake Controller part number 39515 installation instructions and I attached the picture to the right for you to check out.

The flipper switch on the side of the controller does control the aggressiveness of the brake application. With the lever flipped back away from the front of the controller the braking will be delayed, straight down will be normal, and towards the front is aggressive.

Typically 4-way wiring consists of 18 and 16 gauge wires. For a 4-way that has all 16 gauge wire you would want the Wesbar 4-Pole Flat Connector #W787264. The part #HM38138 uses 18 gauge for all wires but the white that uses 16 gauge.
