Re: Mysterious plug near headlight.

That goes to the headlight bulb. That plug has a female companion on the inside
of the housing. Using this setup allows them to pass wires through the housing
with minimal chance of water intrusion. What I can't figure out is that there
appears to be about 16 gage wire leading to the plug, then inside the housing
the wire going to the bulb is about 12 gage. WTF?
