I’m currently wondering if it’s possible to swap out a 1990 GMC Sierra cluster gauge (as seen in picture 1) with the cluster gauge in picture 2. Is this something that has been done before? How hard would it be to do?
It can be done, but compatibility depends on the wiring and connectors. You might need to make some modifications.
I’ve seen people do similar swaps with success. Just make sure to check the pinout and functions of each gauge.
The swap isn’t too hard if you’re handy with wiring. Just take your time and document everything!
