I see what you mean. The two wire low pressure switches are self explanatory. The 3 wires are a different story. On the wiring harness connector plug of the LPS are your wires color coded red/black, black, gray?

Even the GM GP service manual wiring diagram doesn't show the LPS circuit for some unexplained reason. But I'll check again.
