I recently bought a pair of Lockhart Phillips Short Stalk Turn Signals with Dual Filaments. The signals have three wires but the wiring on my bike (98 yzf 600) only has two. I ran two of the wires from the signals and left the other wire unconnected. I have running lights and they flash when i press my turn signals. So, they work. My question is should i ground the unconnected wire? Will having it unconnected short the bulbs or anything else? Thanks, JJP
