Joined some time ago and can’t remember if I introduced myself! My name is Garland andcI am in the process of getting a 78 fj back onthe road and trails. I bought aftermarket turn/ signal lights and they came with 3 wires instead of 2, two greens and a red. I could not get them to work unless I grounded one. Finally took it apart tonight and found the red goes to the small sidemarker. Also found that one of the pedestal screws is longer than the rest and is supposed to touch the bulb reflector and act as a ground, The contact wasn’t good enough and was causing the no work condition! Solution was mark the point of contact, drill it out and run the screw through! They now work perfectly!
