Harness Connection
Doing some maintennance on my rig today and noticed a connector unhooked behind the battery. The truck has been running okay but I am concerned as to what this connector runs. It's a 3-pin connector right behind the battery and below the solenoid. I can't make what color of wires are coming out but I do see a green wire as one of them. I have been having some trouble with my back tank not working correctly, but solved this with a new fuel filter. Any help would be greatly appreciated. I have pics but can't attach them.

Yes, it plugs into a connector on a harness passing underneath the battery. The plug and the receptacle reside between the battery and the smog can bolted to the right fender. I have pics I could email if interested....

<i>but I do see a green wire as one of them</i>
Lt grn/red runs over to the alternator, is it the only one of the three leaving the connector of the three wires in it on the harness side?
Lt-green/red = Charge indicator light relay.
Other two look to be glow plug power/control from alt for diesel engine.
My 94 and 95 has that one, one with the lt-green/red wire going to the alt. Plus another four pin connector that goes no where, back just a little further in the same area. Both have a white cap covering them.
94 is plain jane, 95 has about everything "XLT". I suspect it has something to do with a diesel as well. I didn't look up the wire colors though.
If it is used on yours, that other 4 pin connector, follow the wires and see where they go.

Hi. I posted some more photos if it will help. The three wires snake around behind the intake and interconnect with the main harness over the intake. Third picture shows the color of the three wires.
