    Default Cluster Connector - Single Green with Black and Green Dot Wire

    1980 Mustang wiring question on the gauge cluster.
    Pulled out the dash cluster to replace my speedometer cable and found a green single connector that was not hooked up.
    Any idea where it is to go? It fits the studs on the back of the gauges. Has a black wire with green dots.

    On the back of the cluster on the circuit board there is one stud marked "green" logically I want to put it there, but I also do not want to short anything out.

    I searched through the schematics I have but could find no reference to it.

    In my '80 Mustang EVTM, the only BK/LG D wire going to the instrument cluster connects to the Low Fuel Warning Module.

    I looks like it just connects to one of the studs out of back of the fuel gauge. The one that doesn't connect to that larger connector below is the one, it looks like. Perhaps the one on the right in your picture. (I can't tell if it's connected to that large connector or not. Hard to tell in the pic)

    There is one wire like in the pic that needs to be connected. If not, the low fuel LED stays lit.
    Mine has a right-angle boot connector and is on the green stud.
    Acts like a ground wire if anything. The console LED turns off when wire is connected on the correct stud.
    Hard to get a hand back there to connect everything.
    Short wire harness won't allow cluster to be pulled out very far.

    Thanks
    I also was able to finally find it in the schematics. I plugged it onto the stud marked green in the above picture. Everything seams to work as it should.
