Question about Harley Davidson FXST Softail Standard Motorcycles
The two lights that you have with three wires are for bikes that have "running" lights in addition to the turn signal light in them. The two lights that have two wires are probably for turn signals only. Harley produced a lot of motorcycles that had no running lights at all. Then, they produced a few years with running lights on the rear only. And, finally, running lights on all four corners. Your '88 Softail came with no running lights from the factory. On all four lights, I'm going to guess (without testing that's the best I can do) that the black wire is a ground wire at least on the units with three wires. You'd have to test all the wires on all the units with an ohm meter to see if any of the wires are ground wires. The other wires are for the turn signal wires. I can send you a wiring diagram for a 91 model Softail if you'll drop me a line at [email protected] Don't forget to remind me of what you need.
