VSS = Vehicle Speed Sensor
MAP = Ford MAP sensor with vacuum line hooked to intake manifold
Both VSS & signal wire from MAP are connected to SPDT switch & VSS wire for cruise is installed on the common feed for the switch, so the cruise servo is getting feedback from either the VSS (speed) or MAP (load/MPG).
I haven't programmed anything. I basically did exactly what Jomel Maldonado did initially clear back on page 3. He went a step further by buiding an ardiuno with code to tell the cruise to automatically switch back and forth from VSS or MAP based on upper & lower set speed limits. His setup is "smarter" than mine in that it does this automatically. My setup is all manual. All I have is a Ford MAP sensor, 5 volt regulator, SPDT switch & MPGuino to see live MPG.
