1982 Cruise Control issue/part hunting

[vettejack]

Looks like I'm in the market of a 1982 cruise control part.

In the 1982 shop manual, its identifed as a "resume solenoid valve", with a .5 tan and a .8 black wired plug tongs built into the valve. I found the plug near the left hand side of the firewall, in the engine compartment, but no idea where this valve is nor even how it looks. My mechanic and I cannot find the valve. We're sure its missing, so now we're on the hunt for one! It seems to be the only item left to replace in order for the cruise control to finally work.

I need help in locating one...this "resume solenoid valve"! Or...am I completely missing something concerning this 'resume solenoid valve'??

Thanks!
