Question:
2012 VW Touareg TDI Factory pre-wired Class III / 4 hitch Is 118509 correct harness Trailer has seven pin I will install 39510

Helpful Expert Reply:
The correct 4-way trailer wiring harness you'd need for your 2012 Volkswagen Touareg is actually the part # 118668.
From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well.
Then for a brake controller you could use the # 39510 and you'd be set.
