I have a 2002 BMW X5 without DSP, I have an aftermarket amp with an Audio Control EQS and running into wierd issues with my factory outputs.

I can't for the life of me find an X5 audio wiring diagram. I am looking for the colors of the following factory output wires:

Front Right + output
Front Right - output

Front Left + output
Front Left - output

Rear Right + output
Rear Right - output

Rear Left + output
Rear Left - output

I am looking for all of these, my audio control EQS allows me to connect the regular wires instead of having to convert them to RCA's I think I have it all right but I am sure my channels are all over the place and am getting wierd noise depending on what channel I use. I am sure my stuff is fubar but I can't even begin to verify I have my factory outputs figured out.
