Is it wrapped in a yellow sheath? There was a bad batch out there that were, and the harness was miswired. Those came from LMC, but they could be the same as the AAW.

For a dual headlight system you need two relays, right? One triggered by the light green, one triggered by the brown. Or so I remember.
