What do you do with the power steering pressure switch?

Hi All:

After searching the forum I found several posts that helped me identify the power steering pressure switch wire that is now dangling near the front of my motor.

What do I do with it.... I assume I'll either leave it open circuit, or ground it based on whatever the "happy" state of the switch is.

Thanks... Jeff

Jeff,
I left mine unconnected and idle is good. I believe that it bumps the idle up if you have low pressure to help power steering during parking maneuvers.

Thanks Bob:

That makes sense.
I wish there was a simple "Theory of Operation" that explained all these various wiring elements. It would make it much easier to decide what to do with them.

The pressure switch tell the ECU when the pressure goes up and loads the engine. The ECU then adds to the IAC pulsewidth to compensate for the lower idle.
