Making a 88-91 dash work on a 92-94

[cocodaddy]

Hey fam, if you don’t know the gauge cluster hookup for 88-91 and 92-94 are actually different. I bought a uncracked dash from fb under the assumption it was a 92. After removing mine I realized the hole where the gauge cluster hookup comes thru is actually different! So, my plan is as follows, to remove the area around my old dash where the hookup comes thru and remove the same area on the 88-91 dash, maybe in plastic weld it in place and then brace it throughly with some metal and pop rivets. Does anybody have any experience with this? It’s so hard trying to find a correct dash as everybody labels them as 88-94 when that just isn’t the case. If you have any tips please let me know!

first pic is 88-91 hookup, second is 92-94 hookup,

Why not just swap the dash connectors and use the later model instrument cluster?

I think the cluster hookup is wired into the loom and there isn’t a place to disconnect it from it

Somebody in a gmt400/obs fb group came up with this as a solution. I’m thinking of taking a different approach however.

If the pigtail in the truck was a few inches longer it wouldn't be a problem, But I know they are barely long enough to work with the original dash.

When I cluster swapped my 88. I just trimmed out enough for the later year connector to somewhat fit.

But I think ill do something like the last pic whenever I get a chance

Because it wouldn't work. He would have to add a VSS buffer module and move a lot more than just the cluster connector terminals around.

What else has to be moved?
