my car is an 83 300sd, I bought a 87 420sel for the interour and other nick nacks, my problem is this; I have the Mercedes-benz service manual chassis and body series 126. I'm at job #82-865 ( above title). The lower part of the page has two pictures, Switch, left and switch, right. I think the left is right and the right is left. they have it backwards, I think.My car has soldered pin sockets and the switches from the 420 has switch with plugged in harness. I'm trying to figure out also what this statment means. " the harness without red/white line(1st version) requires a bridge between connectionA and B. On lefthand switch from connection A(no.4) to connection B(no.3) on righthand switch fromconnection A(no.3) to connectionB(no.4)," Now because they have the pictures backwards, I'm more cofused the normal, I also struggle with electrics, so any one who could help me understand how to do this swap of switches, I'd be very greatful. steve
