Question:
This is in regard to Troubleshooting Trailer Wiring Harness with Turn Signals Not Working On 2017 VW Tiguan Continuing from previous Expert Reply . . . As you can surmise, Im not the installer/electrician. His name is Ken, quite a nice and intelligent guy. Anyway, Ken very kindly let me record this video which explains in his view what is missing from the Tekonsha kit. My understanding is that the fault is NOT the circuit board he also checked for bent pins etc but rather there are two wires missing red and brown. Heres a short video where he explains it. Btw, you guys are an amazing ecommerce company focused on customer service. Its something I teach in my classes. Im a university professor in New Hampshire.

To confirm it is a controller module (circuit board) issue with harness # 118675, I recommend double checking your connectors to make sure there isn't a bent pin and the connections are tight and then making sure the ground connection is bare metal where connected. Then using a circuit tester like # PTW2992 you can confirm power is getting into the black box from the connections but not exiting it correctly. If it is receiving but not sending correctly then it is a faulty module.
