S9002 is the BWD switch for the 1979 and prior solenoid valve system. This switch will not work on the motorized valve without a bunch of work building a pair of relays into the circuit.

DEPRESS FULLY is emblazoned on the momentary switch GM used for the motorized valve from 1981-1986. It's not for the 1980 & prior solenoid valve system. There are several negatives associated with that switch and the motorized valve. If you aren't doing a concourse restoration on a 1981-1986 truck then don't use one of these with the motorized valve.

I recommend the plain face ON-ON switch GM used on the 1987 TBI R1500-R3500 & V1500-V3500 squarebody trucks for 1981 and later installs and retrofits of older solenoid valve equipped trucks. Standard Motor Products D-1807 or AC Delco D7089C.

You're looking at how to replace the 1980 and prior solenoid system with the 1981 and newer motorized valve system...

Has your old 6 port solenoid valve failed?
Are you sure it's not a failed dash switch?
