keyless entry 1997 programming instructions

Hello
I just bought my wife a 1997 Park Avenue (non ultra)
It came with only one remote key fob.
I had just picked one up one Ebay and would like to know how to programm it without messing up the working one.
And where can I find the data link connector ?
Thank You
Marty

under dash below steering column. might be a 12 pin connecter black in color.should be right out in open for easy access.when you jump wires door lock will lock ,then you know you have the right two pin holes

try pressing lock and unlock buttons on remote
for 8 seconds until horn beeps

What is the fused jumper wire mentioned in the FOB programming at the top of the page?

its just a wire with a 3 amp fuse in series (to prevent accidentally shorting something out). I just used a paper clip.
