everything is related to the 1990 electronics in my 82 trans am. yes I am aware of how everything works and if I spin the vss sensor with my ignition key in run position the speedometer works however the odometer never moves

Speedo

you can spin it forever as the thing works off a magnet component works that way, do the other guages and such work ?. is the Speed sensor in the tranny new or old ?
