I have finally completed the purchase of two each; Reatta/Riviera & Senoma digital instrument clusters for potential install in my 86GT.

Question; has anyone done either one of these installs in the past and if so could you share lessons learned and any install information you might have.

Thanks

I believe the Reatta and Riviera used different guage clusters. I'm pretty sure someone did a Reatta swap. Sonoma/S 10 swaps have been done. I'd say, either do a search for "Reatta" or "S10" or try Google/Ask.com.

The Riveria and Reatta digital gauges are the same UB3 units. I have checked them out.
I have a UB3 from a 92 Riv. in excellent shape. The pin-outs are the same for the 90-92
Olds UB3 dash. Which is currently in my 88 Formula. The only problem is with the Tach,
it says the white wire is for the tach, but it doesn't work. Haven't tried it with a Buick/Olds
cpu and 3800.
