I'm thinking about installing a kill switch and interrupting the crank position signal as the way to do it. Just wondering what pin/wire of the comp/harness is the crank position sensor's on an 07 2.0 duratec? I'll run a relay in line for the sensor and control it's ground through the kill switch. Also, other than throwing a code, are there other problems that this could create? Like, does the sensor need to be recalibrated or anything when the switch is used? Or does everything go back to normal once the wire is "reconnected"?
