It's the PS pressure switch, which is connected to the idle 
stabilizer. To help prevent stalling when steering at low speeds for 
parking, I guess. On mine, the White/Yellow is on driver's side, 
Red&White, pass. side, although I don't think matters much, since it 
just an on/off switch thing.

Bentley shows (page 97.125) both wires coming from the Idle 
Stabilizer Control Unit, which I think is in the pass side area where 
the aiur intake is, right? But it gives no obvious way to tell the 
connectors on the switch end apart, so I assume it doesn't matter.
