Need HELP IDing wire under the hood - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**ScottH** · 04-15-2017, 11:30 PM

Pretty much done with my 87 V10 but have 1 wire under the hood that I have no idea what it goes to. It is behind the drivers side headlights and comes from the headlight harness. It is tan in color, has a small bracket attached to it, & the end is cut off.

If anyone can shed some light as to where or what this connects I would really appreciate it. I checked wiring diagrams but nothing jumps out to me that might explain it.

Any info is greatly appreciated.

Thanks
Scott

Check to see if it fell of your proportioning valve towards the front of the vehicle in the frame. Kinda looks like that kinda plug
