relay ???
 

I have a 1989 560sl. The seat belt light is driving me nuts!!:mad::mad: The wiring looks good to the belt assemblys. There is a relay somewere. Does anyone know where? In addition, the buzzer would not turn off unless the belt were fastened......even when the car was turned off! That was fixed my disconnecting the plug under the seat.

Thanks Mike

I believe it's one of the relays near the brake pedal.

Thanks, I am going to take a look today!

Thanks! Found the relay and gave it a smack. Light turned off and is working nomally. It is located right by the brake pedal assembly with a electrical connector on the bottom.
