Hello from Buffalo, New York!
I'm swapping out my stock front signals for the Joker Machine LEDs and have a simple question for you guys who have done this job before. Joker Machine signals come with two wires, a red and a black. The plug that the stock signals were attached to has three wires: purple, blue, and black. I'm guessing that one of them is a ground and the other two will get soldered to the red and black wires from the Joker Machine signals. Anybody know which wire goes to which? Any help would be appreciated. BTW my bike's a 2008 Street Bob.
Thanks!

 

That won't work. LEDs can be run as either running lights or turn signals, but not both. If you connect both it will just be a running light.

Blue = Running Light
Purple = Signal Light
Black = Ground
