I just bought an 1983 930 and I didn't check the lights when I bought the car so here's the problem. When I turn the lights on, the power that should be going to the rear marker lights are going to the reverse lights instead. When the lights are off and I put the car in reverse, the reverse lights do NOT light. Can anyone give me any hints as to where the harness plugs are? Towards the front or in the engine bay area? I took the fuse for the front/rear marker lights out and the reverse lights turned off together with the front marker lights. This is how I know that there are plugs crossed somewhere.

Thanks for any help/hints.

Benny.
