Factory harness did not use a black wire for any of the 3 MAP sensor wires.
MAP Signal - LT GRN - Red 32
MAP 5V Ref - GRA - Blue 48
MAP Low Ref - Tan - Blue 54

I have an after market harness, I will take a look tomorrow i have a purple and a tan from the obd2 port, and on a diagram i was checking it say the purple is the Class 2 serial data that goes to blue 58, and on a another says the tan goes to blue 58 so i got confuse, and from the map i have a black wire i will take a look tomorrow to make sure.

Ok from my map sensor i have a lt green, gray, and orange with black. I can't find where to plug the orange with black, and a tan wire coming from the Obd2 port.

I have a purple coming from the obd2 port that is named like serial data.

I just wired an OBD2 plug on a 98 harness, its the purple serial class 2 that feeds the connector, not the tan serial wire.
