:waving:The rear suspensionwarning light is in the tach. The is no speed sensor in the speedometer for the rear suspension as the warning light is activated by a pressure switch. Since the rear suspension on the '83 Standard and Interstate can be run 0-57 PSI there was no need for the warning light so it was changed to an OD (overdrive) light which is on when in 5th gear.I believe there are two speed sensors in the speedo on an '82, one for the turn signal cancel and the other for the rear air suspension. I recall mention of the turn signal cancel control box being under the false tank.
