razr89a, the OP didn't ask about aftermarket systems. Please try to answer the questions not make more.

I did some research on the old forum and found conflicting results. Since our Techinfo isn't completed yet, try both of these:

To reprogram your keyless entry system for a new key fob:
1) Turn ignition to OFF.
2) Ground pin 1 of the Data Link Connector (black 16-pin connector under dash driver's side). Pin 4 of this connector is a ground, so placing a jumper wire between pins 1 & 4 will accomplish this. Grounding pin 1 tells the system you are getting ready to reprogram it.
3) Close all the doors.
4) Turn the key to ACC, then back to OFF. The power locks will lock/unlock. The system is now ready to be programmed.
5) Press a button on your key fob.
6) If you have two key fobs, press a button on the second fob within 1 minute of pressing a button on the first one. Both must be programmed at the same time. If you only have one remote, press a button on it 2 more times to signal that you only have one.
7) The doors will lock/unlock to signal that the codes were received.
8) Remove the connection between pins 1 & 4.

I found that the power locks locked and unlocked immediately upon jumping pin 1 to pin 4. The system was ready to be programmed. steps 3 & 4 were unnecessary.

PROGRAMMING PROCEDURE
TRANSMITTER & RAC PROGRAMMING
NOTE: Following procedure must be performed when replacing RAC
module or either transmitter.
1) Turn ignition switch to OFF position. Use a fused jumper
wire and connect Data Link Connector (DLC) terminals 4 (Black wire)
and 8 (Black/White wire). See Fig. 1. Door locks, fuel door and trunk
lid release should activate in approximately 2 seconds.
2) Press any button on one transmitter. Door locks, fuel door
and trunk lid release should activate in approximately 2 seconds.
First transmitter is now programmed. Repeat this step using other
transmitter. If only one transmitter is being used, disconnect jumper
wire from DLC. If module does not accept programming, see
RAC MODULE CANNOT BE PROGRAMMED under TROUBLE SHOOTING.

Which option worked?

I actually searched on google and found word for word the first one you posted. That is actually for a '94-'95 OBD1.5 with the 16-pin connector. I then google the ALDL OBD1 (12-pin) pin outs to find out what to jumper.

1. Locate the ALDL connector on the drivers side, under the dash. It should look like the pic below.



2. Grounding Pin G (bottom left) tells the system you are getting ready to reprogram a key fob. Pin A (top right) of the connector is a ground, so using a paper clip as a jumper between pins G and A will accomplish this. Once pin G is grounded the power locks will lock/unlock telling you the system is ready to be programmed.



2. If programing one key fob - press any key 3 times. If you have two key fobs, both must be programmed at the same time. Press any button on key fob 1, then press any button on key fob 2 within 1 minute of pressing a button on key fob 1. If the key fob was programmed correctly the power locks will lock/unlock.

3. Remove the paper clip from the ALDL connector and test the key fob(s).
