SOURCE: Map sensor wiring for Chevy s-10

Well after looking it up it's the the map input wire is light green on both 4 and 6 cylinder models.

On a 4cyl the map has black gray and light green, the black is ground, the gray is a 5 volt refrence from the pcm(power control module), and the light green goes to to ECU for MAP input.

On a 6cyl the map has black gray and light green, the black is goes to the automatic transmission, gray is a 5 volt refrence from the pcm(power control module), and the light green goes to to ECU for MAP input.

Hope this helps and good luck

You may need a wiring diagram to make sure, but I think the gray wire is reference voltage and it also powers the throttle position sensor. The sensors get power from the engine computer.
