[QUOTE="AnotherS197GT, post: 15702684, member: 162206"] I recently got the Cruise Control functioning: There are several things the Coyote PCM looks for when engaging the cruise control. There are two switches inside the Coyote brake pedal switch that trigger two PIDs, BOO1 and BOO2. Both must be off for the CC to activate. It also looks for clutch pedal position. For BOO1, I just have pin 13 on the body harness feeding input from the cruise deactivator on the brake pedal. Because this wire also feeds the ABS module, I ended up clipping the wire that feeds the ABS/PCM and wiring it to a relay. The wire leading to the ABS module is on the 87 terminal so that it will function like stock, and my second wire that will deactivate the cruise is on 87a on the relay. This allows the brake pedal to send the right information to the ABS module and the right info to the PCM, even though they require opposite signals. For BOO2, I have pin 39 (3V, white wire, speed control deactivator) pinned into pin 46 on the Coyote PCM. This lets the system see that BOO2 is off when the clutch is up, and on when the clutch is depressed. This also lets me shut the cruise off with the clutch pedal. The only "problem" I have is that sometimes the security light blinks at me when using the set buttons for the CC. I don't use the CC frequently, but I do take a few long trips every year. It will be nice to have the CC working again for those. It gets tiring holding the accelerator for 1200+ miles! [/QUOTE]
