2007 SD 6.0L - MAP sensor circuit ?s
I've been searching for days trying to find the wiring diagram or color codes for the 3-wire plug to the M.A.P. sensor. I believe the middle wire which is Lt green/ Black is the signal wire to the PCM, while the White/ Brown wire is 5.0v constant. Not sure where the grey/ red wire goes to. JSM84

Thanks for the diagrams, too bad they don't show the color for each wire. Had a local mechanic hook up a Multitester voltage meter to each of the 3 wires, which is how we found the 5.0v constant power. But the othe rtwo wires don't show any difference betwen them when changing the engine RPM, with a voltage reading of about 0.48v. I did find a better wiring siagram in the Tech Articles, but even that does not show wire colors.
