Does the car have the cruise control transducer on the driver side fender, with the speedo cables on it?
This being an '82 w/Crossfire, I'm not all that familiar with the complete cruize set-up, but I can't remember ANY separate component for one other than the transducer, and the vacuum servo. Are ya'll certain the plug doesn't go to the transducer?
Then you have the "dump" valve that is actuated by the brake pedal, under the dash.
I may have to dig out some old manuals! Hopefully, someone else with an '82 can help more....
