Help with rear windo defroster switch...
I screwed up the install of a new switch for the rear defroster on my '80 399SD. Now I have 4 wires out of the plug-in; BLACK, BROWN, BLUE, and RED/BLACK.
Can someone please tell me the proper position on the connector for these wires. As a point of reference, assume I am looking at the front of the switch. Starting left-to-right, which color wire goes to which terminal?
Sorry for the dumb question -- I know better than to take something apart without making my own diagram -- but I do appreciate any and all help.
