This is what I have saved in my notes but I no longer have working links to where it was posted. From this you can figure out the swap both ways. "Move B15 to B11, Move A10 to A9, move A11 to A10." That's for putting a '91 cluster into a '90 (same as 88-89)

Connection problems where the instrument panel plugs onto the dash are common on these panels. Do not aggressively clean the connection or it may give you more problems. Some people say one use a pencil eraser to clean the panel contacts. My best luck with cleaning poor connections is to use very fine polishing paper and then very lightly grease them tuner cleaner lube. I started building a list of numbers but don't have many.

Re: 91 chevy wiring
It looks like about a year ago I had my gauge cluster out to try and correct some problems. I resoldered the path of the oil pressure gauge and speedo and thought I had it. On circuit boards like this you can sometimes see micro-opens with something like a jeweler's loupe. I thought I had mine fixed but it still has an intermittent problem; more so during colder weather. When it's warm the gauges react more stable. I haven't gotten back to it and I give it the "Fonzie whack" like I stated before when it acts up.

Re: 91 chevy wiring
The "sweep" gauges have a different connector than the "moonies". It's an important point to make. I found out the hard way since it wasn't mentioned. It's harder to get these parts now.
