M1008 wiring help

[Hammy]

I've looked through the diagrams and I cant find this wire anywhere. the truck runs fine but seeing a random unhooked wire always concerns me. heres a picture below.

the wire comes out of the same harness as the glow plugs and alternator wires.

any help would be great thanks!

What color is it and what does it have on the end?

 

[Hammy]

it's black with a white stripe and it has a ring terminal on it. my first impression is that it's a ground of some kind. I tried to circle it in the photo.

On Schematic F-11 (Diagnostics Circuits) it is shown on the drivers side alternator ground stud.

You do not need it connected unless you have a military STE/ICE tester.

Is that green wire attached to the frame or is it just looping back to the glow plug? Lighting makes it hard to tell.

 

[doghead]

It's looping.

I blew it up to look closer.

thanks for the help! its always unsettling to find loose wires in the engine compartment. I'm glad it's nothing major though.
