Re: Instrument Panel Differences???

You'd need the printed circuits from the tach cluster. If you are swapping from a same year (or close to the 90) everything else would work the same I believe...

Re: Instrument Panel Differences???

Lots of factory Tach info here . That page says
Quote:
87 EFI trucks, 87-91 Blazers/Suburbans: Cannot install tachometer cluster because of speed sensor (VSS) feedback needed for the factory EFI computer and ABS brakes (90-91).
That's not to say something couldn't be made to work.
