Question:
Hi, what is the difference between the 119147 harness and the 119190 harness. I have a 2013 Audi Q7, will either harness work? Thanks.

The trailer wiring harness I recommend for 2013 Audi Q7 is the Upgraded Heavy Duty ModuLite Circuit Protected Vehicle Wiring Harness part # 119190 which is for just the harness or part # 119190KIT which is for the kit which includes wire connections, wire, and a circuit tester. The reason you must use this harness is because the Audi Q7 has a pulse width modulation feature that not all harnesses can decipher.
The Upgraded Modulite Vehicle Wiring Harness with 4 Pole Trailer Connector part # 119147 won't work.
