> Maybe the brown plug is the remote turn on. Did you check any Audi forums? [Crutchfield.com](http://Crutchfield.com) might have some different harnesses you can look at to compare. What kinda speaker system is in the car? Shouldn’t be that hard to figure out, just gotta dig up some more information.

I have tried connecting the remote turn-on to that brown wire and it was a no go. Yes, I have searched every Audi forum I can find and every one seems to have a different answer. I got everything from Crutchfield and this is the harness they provided me. The stock speakers? I actually ordered some Polk’s to replace all the stock speakers but I would like to get the HU working before I move on to that stuff.

> i install car audio products daily and have no clue what the hell you’re using that relay for. haven’t seen that one yet. the blue with white stripe is your remote turn on from the radio. yes you have a factory amp. get me a year make and model and i’ll try my very best for some wiring diagrams for you. and if you could clarify the wire colors you have in that audi harness it would be nice too.

check your PM’s
