I've got a 2003 CLK500, and there's a little 2 wire connector ( Green/yellow, and Green/Red ) that runs from the left side front headlight area, just under the radiator support, and just ends about a foot after it threads under the neck of the windshield washer bottle. I don't see anything that it could connect too within it's reach.
Anyone know ?? Anyone have an electrical diagram for this car ??

Thanks
