Instrument/gauge cluster wiring problems

[djt]

I've already done the 4.0 swap and it runs great. I have the whole wiring harness for a '97 in an '88, but i want to go back with the '88 gauges. I need either cluster wiring diagrams for both or diagram showing which wires to splice into which. I found a diagram showing which wires to splice a few months ago but I can't find it anywhere. Please help cause i need to get it done asap.
