My thanks to all who provided advice.

While I have the dash opened up again I was also going to test all the cruise wiring for continuity and proper grounds. My stop lights work fine, before anyone asks!

How does one test the actuator? I did clean the contacts on the wiring connector for it beside the tach amp, but it made no difference. I did put some kleenex in the top of the tach amp and fixed by juddering tach needle!

I can't figure out how to observe cruise amp operation with a DVM under the hood unless you sit on top of the engine while someone else drives the car down the road at 40 mph!!
