The rear turn signals on the 81' R100 is in the process of deleting . The whole rear light section has been re-wired, and only the tail light remained. After that, the front wont work as well. They will all work again if the rear plugged back in. Looking into the wiring diagrams, it looks like the real section is a stand alone section, and it should make no affect to the rest of the circuit. I might miss something very easy here, so please show me the light.
