Tekonsha P3 wiring harness / interface with FORD harness

[Bigshow]

I just bought a P3 and it has a harness in the box that plugs into the controller and the other end just has the loose wire ends. My truck came with a harness that plugs in somewhere on the truck (I have to read instructions on that) with loose wire ends as well? Is there a harness that would plug at each end and eliminate the wire connecting? Its the 2003 truck in my signature.

Hello, The 2003 Super Duty has a plug under the dash, just to the right of the steering wheel, that the controller plugs in to. You'll need to take that access cover off under your steering wheel to see it. Look to the right in that opening. The Tekonsha Prodigy's I've purchased had instructions on how to connect their connector to the factory ford connector (loose wires to loose wires), however, you can purchase a custom pre-made harness for your truck that is plug-and-play. I've seen them on Ebay and E-trailer for not a lot of $$'s.

Yeah, don't mess with the loose wires, just get the converter plug. It maeks it a "plug and play" process.

etrailers shows the bare pigtails that come with the trucks already.

Tekonsha open the pdf. It shows complete adapters. It looks like it may be the 3035P, although it say's "excludes Super Duty". Looks like it may mean the 2008 SD, as another p/n includes the 2008.
