A/C Switch on Compressor

Does anyone know where to wire the high pressure switch on the compressor to. I am adding back in A/C and cant figure it out. Its not in any wiring diagrams that I have looked at. Its a single wire that attaches with a plug in thats the same as a knock sensor. I have everything to do what I need to do except everything to do with that wire.

One side of the switch goes to D12 on the ECM.

The other side goes to ground.

If any of the original wire to the ECM is still there it should be dark blue.

Fog lights are not driving lights. Turn em off slow pokes.
