Does anyone know the pinot for the 90/91 cluster swap into a 88?

If I got this right 1988 trucks cluster 1/2, 3/4 Ton, 1992 1 ton Suburban cluster same speedo next gen.

If your 87,88,89,90,91 1/2, 3/4, 1Ton Suburban cluster same 81-87 truck 1/2, 3/4 Ton a lot same few key parts changes.

Hope this answer your question: Direct fit would be under lined. with a un-touched cluster you will have look closely. If you want a direct factory replacement.( of the same OPTION on your Suburban.)

The 90 cluster is electronic, even though it looks the same. 80-87 C/K trucks and 80-90 Suburban clusters are the same an will swap around. 73-80 had differences, and you must be careful with those. Only difference is the Suburbans had trip counters in the later speedometers.

i remember tearing apart a 89 1ton years ago and it had a goofy sensor in the back of the speedometer, kinda looked like a electric eye that twisted into the back of the gauge, and i was told it was a VSS. ever hear of anything like that?

i think its the one i have in my 86 now, its got the trip but its broken

Yes, that would be a VSS (Vehicle Speed Sensor). I believe they were first used in these trucks starting around 1983 when equipped with cruise control. I think they were also used for the engine control system on 87+ trucks with fuel injection.

When the electronic speedometers were introduced, the VSS was moved down to the transmission where it took the place of the speedometer cable drive.
