I can't see so good on this pic, but could it be the connection for a windshield washer pump? The general placement is where my (non connected wire is), the previous owner removed the pump on my truck (man, the worst rust in my truck is under the windshield washer fluid reservoir) just a guess though
I think your right....I should have noticed that the washer bottle was missing due to he inner fenders being cut.
yep . . . 100 % positive that all these are correct, I checked my plug-in, it is exactly the same except mine connects to something ! L o w N l o u d
