Question:
I bought a Tekonsha Prodigy P3 trailer brake controller with a custom harness for my 2006. The harness I got is too short. Do you guys have a longer harness?

Hello Rick, we sure do. For a longer harness for the Tekonsha P3 Controller you can use the following:
- Pigtail Wiring Harness for Tekonsha and Draw-Tite Brake Controllers - 34" Long # 7894
Or if you have some extra wire laying around you could use a length of wire and a few heat shrink butt connectors and make your own extended harness.
