H2O sensor help for Grand Prix

[WAYNAGEN]

I need some help on the wiring for the EFIE for the 2000 Grand prix.
I have 4 wires from the sensor and need a little help for the right wire
I scanned the wiring diagram for extra info for the right wire to splice into going to the computer?
Thanks Waynegrand prix.jpg

Have you tried probing them? Don't always believe a pinout schematic, they are frequently wrong. Use your multimeter and probe for the signal wire.

I believe it should be one of the smaller wires of the four. But agree one should meter it as even your schematic shows Pin A of one and Pin B of the other.

Tan & White wire

Just tested one like this. Out of the 4 wires its the one with the stripe...

Prove it with a meter b4 cutting.
