Instrument cluster interchange question

[Turdle]

Can I use a 91 or 92 cluster in a 93?

Reason I ask, Is I am having issues with my 93. Fuel gauge and temp gauge do not work correctly. Upon investigating I saw a prior attempt at repairing the circuit on these 2 gauges. The fuel gauge is non responsive, and temp gauge pegs. All other gauges work fine as far as I can tell.



So, I swapped in a 91 ( or was it 92?) navajo panel. Now I get alternator pegging to the negative, fuel pegs to way over full as well as oil pressure pegging to the right when the key is switched on. I did not reconnect the speedo cable yet.

seems like a ground issue, but where?

I did notice the color of the ribbon circuit ( mylar film stuff with copper circuits) was different-Navajo is blue and the original is a pink color.

Thanks for reading.

Ok goody
Seems the circuits on the clusters changed from year to year also. I looked both of them over a bit closer, and sure enough the circuit layout on the clusters is different.

for instance on the fuel gauge side of the cluster is a connector. On the 93 cluster the 3rd trace over on the borrom row goes to the fuel gauge.

On the 91 navajo cluster the same trace goes to the low oil light. So not only is the cluster different, so would be the dash harness.

Did you just answer your own question?

I've never gone from a 91/92 to 93, but I have swapped 91 and 92. I've also swapped the bad gauges before too (not just the entire cluster).

I could have sworn that the 1991-1994 were completely interchangable but that may have only been the gauges, not the entire cluster.
