Installing Prodigy P3 Brake Controller in 2017 Chevy Express Van With Factory 7-Way  


We have a 2017 Chevy Express 2500 Cargo with factory trailer package and FACTORY 7-way trailer adapter on the back. We want to install a Prodigy. Do you have wiring instructions for this specific situation? Everything Im finding online is starting from scratch with no factory package.

There are no instructions specific to vehicles available for wiring brake controllers like the Prodigy P3 # 90195, though we do have a video of the P3 being installed on a 2017 Chevy Express which I have linked for you. This video shows it being installed on a van that does not have a factory 7-way, but it will show you what you need to do in terms of wiring the controller.

Having a factory 7-way on your van will limit some of the work you need to do though you are still going to have to connect your wires because having the factory 7-way only means the wires you need are already run for you and there is no plug-and-play adapter available for this vehicle.

There may also be some confusion because there are models of this van that have the wiring up and above the emergency brake pedal or tucked under the driver side floor mat. Some models have the blue brake output wire already run from back to front located under the dash near the emergency brake pedal. On these models, the power wire is not run to the battery, so you will need # 10-1-1 and a circuit breaker # 38630 to run the 12V to your controller.
