Need MAP wiring help 1999 Trans Am
I accidently pulled the wires out of the map plug when removing the intake, so I'm trying to repin the connector and I don't know which wire goes into what position on the connector. 3 pin connector wires are grn, grey, blk. Can anyone help?
Thank You

shoemike, I thought the same thing at first but couldn't figure out what his intake had to do with map lights. I think he meant the MAF (Mass Air Flow) sensor connector.
A = yellow (sensor signal)
B = black with white (ground)
C = pink (ignition power)
The problem is that the wire colors don't match what he said.
Maybe the OP can give us a little more information...

thanks guys, I got it fiugred out. MAP sensor = manifold air pressure, it's a small sensor on the back of the intake manifold by the firewall that's part of the fuel injection.

Ahhhh... the Manifold Absolute Pressure sensor. The connector is the same 3-pin one as the MAF sensor above except for locating pins that prevent getting them mixed up and the wires are:
A = orange with black (sensor ground)
B = light green (sensor signal)
C = gray (sensor 5V reference)
A = orange with black (sensor ground)
B = light green (sensor signal)
C = gray (sensor 5V reference)

It's easy to not realize our cars have one since they hide it behind the manifold. On japanese cars I usually see them mounted on the fire wall
