Brake Controller Recommendation for 2009 Chevy Silverado to Apply Trailer Brakes

Question:

Have 2009 Silverado 2500hd 2 wheel drive. The connector is not getting stop or signal power to the connector. All others work. l/s signal, running lights etc. No power to the red wire. I suspect the harness. Is the replacement harness a plug in or do you have to splice it in like you would a 2002 ?

7-Way trailer connectors do not have a dedicated brake signal ran to them. That signal is carried on the turn signal circuit wires as they are combined. Are you possibly trying to get the brake output circuit active for trailer brakes? For that you'd need a brake controller as that requires carefully applicated voltage to smoothly apply the trailer brakes.

For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes. This will be the last brake controller you buy. It can easily be transferred to future vehicles as well.

No install plug is present under the dash, but the needed wires are already run. You will connect the brake controller wiring with the vehicle wiring already present under the dash. I attached an install video for this as well.

If for some reason the stop light circuit for the brake controller wiring wasn't working the problem would be a blown third brake light fuse under the dash.
