HOW TO: 1993 grand marquis sync keyless remote
 

figured it out!!! heres what i did.

- remove glovebox
- behind, there was a grey connector piece with a grey and a white wire
- turn the car to run
- bend a paperclip and quickly short the wires together
- when i did so, the locks all locked and unlocked
- i started pressing the buttons on my keyless and it synced up and worked!

yaaayyy!!!
