M1097 fuel filter sensor 4 pin

[giphillips]

I’ve got an 08 1097. The fuel filter/water separator has a sensor at the top with 4 wires coming out of it to a connector. I‘m trying to get a pin out of that connector. Any assistance would be greatly appreciated

I am curious why? it is a pressure sensor that is only used with the Diag equipment that nobody uses, it serves no useful purpose.
It is only connected to the Diag port near the shifter, some folks jerk it out and put a pressure gauge there.
