if i put gears in my 91 rs with an electronic speedo that just plugs in (no cable) how do i set up the speedo so it is correct after i change the ring and pinion? Thanks

I believe you need to buy a speed sensor (the one in the tranny) for a car that orginally came with those gears.

The same way you change the speedo gears for a cable driven speedo. The speedo gears are in the tailshaft of the transmission, where the wire plugs into it.
