1988 Cadillac El Dorado instrument cluster lights

my msg. ask if you can help me correct the problem with the lights on the instrument cluster.

Are all of the lights out? Do any of the gauges work?

yesterday I answered the question which you asked. did you get my answer? I have no indication on the instrument cluster so the gauges don't show up. hope you can help me thank you very much for your time

ps. I have taken apart under the dash board and it is impossible to trace the cables. there are 4 cable ends that appear not in use,i.e. maybe other options.

thank you for your response. none of the llights work,i.e.,the whole cluster is blank(no lights). the head lights, interior, and directional all work. you ask if the gauges work ,there is no lights to tell me if they work.
without lightds on the cluster I cannot see the gas odometer.etc. the radio light works. I hope I have provided enough info. please let me know if you need more info.
Again thank you for your help, it's encouraging .

Have you checked under the dash for disconnected wires / connectors... If so and they are all attached, chances are the insturment cluster is bad.

thank you for your reply. I have no way of checking connectors I was hoping to find where one connector went since it was different from the others but ai can't where it goes every thing ,i.e, connectors wiring and bound harrness are too inter tangeled to be able to tell where what goes where. Do you by chance have a way of telling me how power gets to the cluster, or a picture of what the cluster looks like from the back?
again thank you very much for your help I have no idea of determining if the cluster is bad.

I don't have a wiring schematic that I can cut and paste a schematic.
