Question:

Do you have a Tekonsha wire adapter for 2010 GMC Sierra, or does this vehicle require a manual splice into the existing harness?

On your 2010 GMC Sierra no plug is present under the dash for installing a brake controller, 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 a help article and install video that covers this for you to check out as well.

For a brake controller I would recommend the Prodigy P3 Brake Controller part # 90195. 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.
