Question:

I have a 2022 chevy Silverado with an exiting factory break controller. I am installing a tekonsha p 3. Will I need to take my truck I to a dealership to disable the factory break controller? I read somewhere that a 10g wire will be needed. Any guidance would be greatly appreciated!

Hey James, bypassing your integrated controller does require some wire but not a trip to the dealer...

Installing the P3 brake controller # 90195 on your 2022 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.

Hey James, how did the wiring go with the P3 brake controller on your Silverado? Did bypassing the factory controller with the harness and blue wire setup work smoothly? Your update could make it easier for others doing the same upgrade.
