Installing a Tekonsha P2 Trailer Brake Controller on a 2010 Hummer H3T with Factory 7-Way Connector

Published 10/19/2011

Question:

Ive bought a prodigy 90885 and want to install on my hummer is there any harness that I can hook Into or do I have to splice in all the wire. I have a 7way plug from the factory. The brake pedal wire is the one im really concerned about. Any help would be great. Thanks

Since your Hummer H3T came with a factory 7-Way, you will be able to find the tow package wiring under the dash of the vehicle. The wiring should be located to the right of the steering column, under the dash, behind the radio area. The wires should be labeled.

You will splice the brake controller wiring to these wires. On the brake controller, white is ground, black is 12 volt power, blue is output to the trailer brakes, and red is input from the brake switch stop light wire. If there are additional wires on the tow package wiring, they will not be needed for the brake controller and you can tape them up and stow them out of the way.

I have included a link to the installation details for the Tekonsha P2, # 90885, for you.
