Hi all some help please,
One of my fog lamps is not coming on shows up on the dash as bad bulb but i checked the bulb and its good, it's just not getting any power checked the wires back to the four pin connector behind the headlamp and I am getting power on one side of the connector the wire colors and numbers ( Brown-4 I believe is common, white and blue-2 and white and green-1 are the ( POS + ) for the lamps and the other is white and black-3 for the horn,) on the white and green i am getting 11.6v on the white and blue i am getting 1.5v so i am trying to trace the wires back checking them as i go but i am at a loss as to where to look for the next connection point is, Any help would be greatly appreciated thanks.

Ok even if someone knows but don't have the wiring diagram where the next connection point is that will still help me out, I just need a little guide just don't want to go scraping looking that might be counter productive.
