Trailer Wiring Recommendation for a 2012 Audi Q5

Question:

i installed curt 56200 in a 2012 audi Q5. none of the lights work! I have verified power and ground at the module as well as ground of the lights. I even connected a new trailer light kit....i measured voltage at the curt output wires and do get a pulse of voltage on the blinker pins but is it extremely fast, the light bulbs dont even flicker! i tried this with the rear hatch closed.as well

The Curt wiring harness part # C59236 that you referenced has been confirmed as a fit for your 2012 Audi Q5. It sounds like your problem has to be in the way the converter box is wired.

You will want to use a circuit tester like our part # PTW2993 to verify that all of the connections you made to install the harness were to the correct circuits. I attached a video that details how this process was done on a similar vehicle. The wire colors will be different, but the testing process will be the same.
