Brake Controller Harness For 2008 GMC Sierra 2500HD

Updated 11/25/2020 | Published 11/24/2020

Question:

Do you offer a plug and play harness that will work on a 2008 GMC Sierra 2500HD for the Primus IQ brake controller? Or do we need to do some cutting and splicing for this application. Thanks.

It is possible to get your Primus IQ working with your GMC Sierra. While there is not a factory port on your Sierra to plug a custom harness into, and there is therefore no custom harness available, you can still splice into the existing wiring under the dash. If your Sierra doesn't come with a factory 7-Way, then the product I'm recommending is the # PK11898 Pollak 7-Pole, RV-Style Trailer Connector Socket w/ Wiring Harness and Mounting Bracket. You'll find the factory wires you need for splicing this in behind the bumper of your truck. It will meet your needs and will pair very well with your Primus IQ.
