Steps Needed To Set Up P2 Brake Controller in 2003 Silverado with Tow Package  


My 2003 Silverado does not have a factory installed hitch but I did find the wiring harness with the round plug and cap above my spare tire. I was going to purchase the PK11893 connector that I believe will plug directly into this factory round plug. I also need to connect my Tekonsha P2 brake controller. It looks like I should purchase the P2 harness adapter 3015-p. Then I will need to make some connections under the hood. Will I need to run the blue wire from under the hood back to the 7 way connector or does the factory wiring harness handle this? If I do need to run the blue wire back how can I connect the blue wire to the PK11893 as it plugs directly into the factory round plug?


Expert Reply:

Since you have the tow package wiring plug located above the spare tire all you need is a connector like the Replacement Multi-Tow 7-Way and 4-Way Trailer Connector, # 30955. You will just plug the adapter into the factory connector and mount the 7-Way at the rear of the vehicle.

Then you will plug your Tekonsha Prodigy P2 brake controller # 90885 into adapter # 3015-P. The adapter will plug into a port under your dash.

I have included an FAQ video below that should be helpful when you are wiring in a 7-Way. Even with a tow package, there may be some connections that need to be made under the hood. The article covers these steps.
