Someone was being ultra custom on your car. i was attempting to use a relay because crutchfield said i needed it. yeh…they were wrong. fmfkid…thanks for the help. no one had a diagram to help me out so i just went with the good old trial and error method. i have no idea why those wires were cut behind the harness. the guy i bought the car from said the original owner had done that which i find hard to believe. it looks like someone got 2 out of the 3 harnesses needed and just spliced into the extra wiring harness. --- _[View the full topic](https://forums.speedlife.net/t/alpine-h-u-install-on-audi-help/190641)._
