The average duration of each pulse is 10 milliseconds. If vehicle speed drops 5 m.p.h. below set cruise speed, the module will hold the vacuum valve in the completely open (energized) position. If vehicle speed exceeds set cruise speed by 3 m.p.h. or more, then module will hold the vent valve in the open (de-energized) position.. I made this diagram for Clyde65, but thought others might be able to use it. This is just a schematic drawn to hopefully be a little clearer than the factory service manual. This is how to hook up a factory cruise control module for cable throttle body's. It's really fairly simple, you just need to make sure you get the right module.
2. Apply nut and position Control Switch for driver's best view. 3. Assemble (2) 3-pin connectors from the sack parts to the mating wire colors on the Control switch harness. Use the diagram to mate the module harness to switch harness. Figure 12 4. Route the assembled Control Switch harness to the mating connector of the Cruise Control..
