HD Headlight Harness

[mikemileski]

I recently bought one of the aftermarket headlight harnesses from LMC truck that has the relays so I get a full 12 volts to the headlights. It didn't come with any instructions so I called LMC's customer service and the guy told me it was intuitive on how to install it. I can pretty much figure everything out because it is pretty straight forward but there is one connector on the new harness that, for the life of me, I can't find the existing factory connector that it's supposed to plug into. This connector on the new harness is a male 3 prong one with a red, a black and a white wire. I've searched in the areas around both headlights and can't find an existing connection that I can unplug and plug this new one into. Can anyone enlighten me as to where it might be located?
