Kris 90 Report post Posted July 13, 2020 I installed my under dash wiring harness this weekend and there’s a single black wire that is a little behind the gauge plug. Where does this connect. It wasn’t hooked up to anything when I took the car apart. There’s no connector on it and I can’t seem to find it in the wiring diagram. Quote Share this post Link to post Share on other sites

LoneWolf2U 136 Report post Posted July 13, 2020 Ground wire, had a ring end on it and to brace behind guage cluster. Quote Share this post Link to post Share on other sites
Kris 90 Report post Posted July 13, 2020 I was thinking gauge ground also but wasn’t sure where it connected at. It’s not the courtesy light, those are already connected. Quote Share this post Link to post Share on other sites
Midlife 814 Report post Posted July 13, 2020 Nope, it is a blind circuit and the end doesn't attach to anything. So why is it there? It's attached at the dash cluster plug to the violet resistor wire. That wire is a single strand 28 to 32 gauge wire, too small for the pin to crimp onto the single strand. So...simply add another 18 gauge wire to the resistor wire for mechanical strength at the crimp and Bob's your Uncle! Simply tuck that black wire out of the way and be happy.

Kris 90 Report post Posted July 14, 2020 So I think your saying to add from the violet wire and attach it to that wire? Quote Share this post Link to post Share on other sites

Mach1 Driver 560 Report post Posted July 14, 2020 11 hours ago, Midlife said: It already is at the other end of the black wire. What Mid is saying is that terminals have a minimum crimp range. If the wire is too small it will fall out of the terminal. The easiest thing for Ford to do was add a wire to the terminal so the violet resistor wire wouldn't fall out. It gives the terminal something to grab onto. If the end is exposed you probably want to tape it off. Quote Share this post Link to post Share on other sites
