I have not found the answer looking though the forum. I followed the TSM for 75 cj5 and the painless wiring diagram. I connect the the wires correctly to the spartan turn signal unit. I have only the left front turn signal flashing. When I move the switch on the spartan the left flasher is out and no flashing on the right side. The rear does not flash and the running lights work. I am using the painless harness PFR 10150. Any ideas would be helpful!
