Going to put cruise into my truck, got all the stuff from various donors, all GM of course, all 80's. My setup uses so little throttle travel that I'm driving at 60 with my foot at a 90* vertical. Very uncomfortable even on short trips.
Since I have a manual trans, and I'm not using my clutch safety switch, I'm wondering what happens if you ONLY cut voltage to the cruise setup whiel the servo is "energized"?
I need to look up some of the wiring, but it appears that the cruise brake switch both cuts power AND vents vacuum from the servo when you hit the brakes. The way it seems set up, (not connected to anything) when power is cut, it will automatically vent, and it wouldn't hold you at the same speed. That may only appear like that because the electronics switch a valve inside, and without voltage, it's not working as it would in the truck.
I doubt it would happen only having three useable forward gears, and only one useable at highway speeds, but hitting the clutch pedal with cruise on would be a bit exciting. I've already got an RPM limit set, so that's not really an issue, but if I could set it up so I didn't have to hear the engine hit 6200RPM, I'd like to.
