"Homemade" XFI MAP jumper harness??

[NCTURBOS]

I can't find my notes on this... Tap into the green wire at the clear connector under the dash, but does it matter which side of the connector's green wire?? Then run the wire to the MAP connector on the XFI box, but which pin do we use A, B, or C. I was thinking it is pin B.

Per the XFI manual....

Pin A – MAP return, black (tied to ground)

Pin B – MAP signal, white/violet (C20)

Pin C – MAP +5V reference, red (C24)


I would say yes.... Pin B is correct...this should be the correct wire expecting a varying voltage from 0-5 volts based on map input....
