I'm putting a 1993 black dash in my 1988 GT. I have a 140 mph cluster from a 1991 GT, I have been told I will need to re-arrange the wires on the plug for the cluster to make everything work right. Is this true? If true which wires go where?
Schematics would help as I am not a wiring expert by any means!
thanks
Matt

here are the diagrams for the 88 and 91.

let me know if you need the 93. also, let me know if you would like a clearer PDF file of these diagrams. they're about 160kb and the max upload here is 78kb.

i'll email them if you want.

I pm you, so it is true that repinning the plug is needed?

Didn't the 91's have airbags? Are you sure the guage cluster will fit with your current steering column?

I know that in 90 they implemented the airbag. so 90 and above is different than 87-89. I pulled the dash on my 93 and it was simple, but there are two different groups of wiring. Give it a try, you can always put the old dash back. I would aquire a used wiring harness before switching pins and connectors. Might be a bit tricky.

When doing a 4 cyl swap on an 87 we used an all 91 black interior and ran into this problem. This was on a buddies 4 to 8 efi swap... what we did, was swap the circut panels from one cluster to the other. Been so long ago(about 6 years) can't remember exactly if we had to swap any gauges, but want to say we didn't...

I just did it the easy way and swapped the 140MPH speedo into my 1988 cluster and then slapping in some gauge face overlays. No rewiring necessary
