Finalizing Connections for the Electric Trailer Brake Controller on a 2010 Chevy Tahoe  

Question:

Expert Reply:

It is possible that you will need to make a few connections under the hood of your 2010 Chevy Tahoe in order to power some of the brake controller and 7-Way functions.

Under the hood, remove the cover for the power distribution box, located on the drivers side. The ring terminal for brake controller power is located directly to the right of the power distribution box. It is taped to a wiring harness between the driver-side front fender and the power distribution box. Cut the tape to release it from the harness. Then run the wire to the front of the power distribution box and hook the ring on the left post with an M6 stud, # 185916.

The ring terminal for the 12-volt power lead for the 7-way trailer connector is located to the left of the power distribution box. It is taped to a wiring harness under the power brake booster. Cut the tape to release it from the harness. Then run the wire to the front of the power distribution box and hook the ring on the right post with an M8 stud, # 185917.

Tighten the ring terminals onto the posts using nuts. Activate the brake controller power post by inserting an automotive style 30-amp fuse into the correct slot in the power distribution box. Activate the 12-volt power lead post by inserting an automotive style 40-amp fuse into the correct slot in the power distribution box.

Most vehicles are already equipped with the fuses listed above. However, if your vehicle does not have one or both fuses, you will need to insert your own fuses. Place the cover back onto the power distribution box, and close the hood to finish. I have included a link to an FAQ article that covers the above application. You will want the section called Finalizing Connections for the Brake Controller.
