My goal is to put everything possible back stock. First project is the front turn signals. The bike had a rifle fairing and the owner had cut the wiring connectors. I was able to fabricate a way to connect the housing back to the bike. Now I have 3 wires but only 2 posts on the bulb socket to connect to. I'm guessing its ground but where should it terminate?

On the BMW OEM turn signal, the straight male prong is the ground and the bent (inclined) male prong is the power to the light.
In OEM wiring, the ground wire is brown and has a 90-degree female connector, while the power wire is two-color and has a black plastic shroud on its female connector. I remember this because just yesterday I happened to fiddle with my 1995 K75's front turn signals.
Hope this helps!
