i have a 1988 mercedes with a becker deck. i have all the power figured out i just need to know what wires i need for the factory amp. there are 2 plugs i have yet to decifer what they are.
the first is a 5 pin plug pin 5 is brown/blue that has a pigtail on it,pin 4 is a brown that is jumped over to to pin 1. which in turn goes into the harness.pin 3 is green/ black and pin 2 is empty.
the other plug is a 3 wire one with a green brown and blue. i know i will have to use rcas to send the signal to the amp, i have tried everything in my knowledge to try to get it to work. i must be missing a remote turn on or sumthing. any chance anyone would be able to give me a clue as to what goes where. or even a wiring schematic.

 

call a benz dealership, sometimes if you ask really nicely they will help you out.
