Having problems with your 1991 Mercedes-Benz 420 ?

My 1990 420 SEL needs to connect power to a new electric aerial, can you tell me which of the three wires (red/White, brown and Blue) does what as my replacement aerial has only two wires (red and white) ? cheers

Answers :

The blue wire goes to the signal to tel the wiper to go up and down like turning on an amp. Look for a open terminal for antenna power signal.
