Straight out of the service manual, same procedure from 94-98:
Programming, Electronic Door Lock Control Processor
NOTE: The remote keyless entry module erases all previous keyless entry remote transmitters (15K601) from memory when the keyless entry remote transmitters are programmed or reprogrammed. The remote keyless entry module can store up to fourkeyless entry remote transmitters in memory. All keyless entry remote transmitters must be programmed (reprogrammed) at the same time.
To program (or reprogram) keyless entry remote transmitter into the remote keyless entry module, perform the following steps:
Turn ignition switch to RUN or ACC position and momentarily short the two terminals of the Program Connector (two-pin connector next to the remote keyless entry module. Remove LH luggage compartment trim panel to reach the connector). Both doors should lock and then unlock. Remove shorting pin.
Press any button on keyless entry remote transmitter . All front doors should lock and then unlock to verify that keyless entry remote transmitter has been programmed.
If door locks do not respond, press button again (up to three times maximum with the same keyless entry remote transmitter ). If door locks still fail to respond, go to Pinpoint Test A.
Repeat Step 2 to program additional keyless entry remote transmitters into the remote keyless entry module (up to a maximum of four keyless entry remote transmitters ).
Turn ignition switch OFF. Both doors should lock and then unlock.
