I'm trying to figure out why the light for my instrument cluster doesn't work. I replaced the bulb, it wasn't connected to the back of the instrument cluster it is just dangling loose under the dash. I assume this light should come on when I turn on the headlights. It's difficult to trace exactly where the wire goes to. It is taped together with a wire that goes to an improvised horn button mounted on the side of the steering column. There's at least a full roll of electrical tape up in there. It then seems like it may go over to the headlight switch, but somewhere along the way I think the wire was added on to with a different color wire because I don't see the gray wire from the bulb end coming out of all the wires that are taped together. Everything else headlights, tail lights, dome light, signals and horn work fine. Can anyone give me a suggestion as to how to troubleshoot this problem. Or tell me how the instrument light should be connected if I just need to re-wire it. In case you can't tell I am electrically challenged. Any help would be very appreciated. Thanks - Al
