I then decided to make sure that the ground was good and reverse the wires. Connecting the ground to the sensor leads, and the positive side to the hot side of the battery.
I found that I have a good ground. While testing this way with the ground side of the multimeter going to the middle wire of the sensor lead or plug, and the positive side going to the hot side of the battery it shows 5volts. So is that the signal wire? and should it test showing voltage hooked up this way?
Hooked either way the third wire shows nothing. please let me know if that helps you understand what im talking about.

the ground lead of meter goes to ground. the positive red probe of meter goes to the MAP sensor wires to be measured. you do not put the meter on the battery positive when measuring the MAP voltages..
black is ground ///////////middle is output \\\\\\\\\ wire on the other end is the voltage input of 5 volts my be pink ..
