Even though the 1991 and 1993 tailgate covers look the same, one used four hidden clips to attach - the other one uses two screws...
There was a reason why I simply unplugged the "gate ajar" sensor - it is a PITA to get to. (anyone know the part number btw? will need a new one).
The car "feels" much safer now that half the idiot lights are off - no oil warning light, no low oil light... Now I just need to safe up for the ABS sensors...
