Unleasehed, I read the instructions again, looks like the map sensor is supposed to be supplied with 5 volts. It says to tap into supply voltage at the tps, maf, or map. Those sensors are fed 5 volts.
Is it safe to tap into one of these?
The output of the sensor is 0-5v on the boost/vacuum set up for the 3 bar map. It does require sourcing 12 volts for power purposes. I installed a raptor shift light and just used the supply voltage signals from the cpu. You can pull the 12v from any source.
