Is There Plug-In Wire Harness For Prodigy P3 Brake Controller on 2020 Audi Q7 w/ Tow Package

Question

Question:

I need a brake controller for my 2020 Audi Q7, it is pre wired with Tow package. I really like the Tekonsha P3, but your website only lists the P2 with a bundled wire harness to make installation a breeze. I am not real confident with splicing into my cars wires. Can I get the P3 WITH the appropriate wiring harness for my vehicle?

I certainly don't blame you for not wanting to splice any wiring, and I can verify for you that there is indeed a plug-in wiring harness for the P3 brake controller and your 2020 Audi Q7. What you will need are the following:

- Tekonsha Prodigy P3 Trailer Brake Controller # 90195

- Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers # TK22FR

You made a superb choice with the Prodigy P3 because it combines a high level of performance with reliability and ease of use. And since your Q7 has the tow package, you're completely set, and don't need any other parts you can just plug it right in and you're ready to go.
