Also... for your '92.
- The valet key wiring changed from two to three wires for '91 and up.
- The oil level sensor connector was added for '91 and up.
- The EVAP solenoid connector was moved from the chassis to under the plenum in '91.

Like Jeff said, none of these things matter to you. You can just add a 645 ohm resistor to the ECM connector to simulate the Valet key as always in full power mode and avoid the valet wiring error code.
