Can Prodigy P3 Brake Controller Replace Integrated Controller of 2015 Chevy Silverado

Question:

I will be installing a disc brake conversion on my fifth wheel. My truck, a 2015, Chevy 3500 Duramax has the factory installed brake controller. I want to use the Tekonsha P3 since I feel it is more reliable and has better features instead of using an HBA-CAM with the Hydrastar. Will my truck had the quick connect under the dash or do I need to splice everything in and is there a disabling process I need to complete for the unused factory system.

Installing the P3 brake controller # 90195 on your 2015 Chevy Silverado 2500 with factory integrated controller will actually be very simple.

What you will do is use harness # 3016 which plugs into a port on the truck already. But you will need to remove the blue wire from the end that plugs into the truck. You will then take a length of wire, # 10-1-1, and connect it to the blue wire you removed from the connector.

Route the blue wire through the firewall, under the truck, and to the trailer connector. Avoid hot or moving parts like suspension and exhaust.

At the trailer connector, remove the wire in the 7 oclock position (looking at the back of the connector where the wires attach). Tape it up and stow it out of the way. Then attach the wire you ran to the 7 oclock position. This will bypass the factory controller without causing any dash lights/error messages to appear.

The 10-1-1 wire is sold in lengths of 1 foot. So if you needed 20 feet you would put 20 in the quantity box.
