I believe its for the cruise control on tbi cars. I don't know for sure,but I do know my old 87 tpi iroc didn't have it but my 88 305 tbi bird did.

Re: Connector On High Pressure Steering Line??
It's the P/S high-pressure switch on TBI and V6 MPFI engines that signals to the ECM that the driver is holding the steering wheel in a lock (trying to explode the pump) and the ECM increases the idle speed to compensate for the extra load from the fuel pump.
Carbed engines or TPI cars don't have this switch.
Hope this helps.
