The FTP switch came on a number of Caddies, not just the FW. I got one off of a 94 and a 96 (the first switch was not functioning). The FTP switch on most of the Caddies is the same unit. It bolts on to the OEM column, and if you swap the wires for the high an low beams and hook up a hot lead to the "new" connector it is an easy mod. If you remove one of the "pins" from a donor connector (with 8-10 inches of wire on it), you can insert it into the original connector on your car (there is a space for it), and then all you have to do is splice a wire to one of the red wires coming to the ignition switch. I swapped the column, because my OEM column was not working right, I was removing the dash for other reasons, and I thought it would be easier to do everything at once...there were issues, as usual. On the other hand it was not all that bad either. I just had a learning experience (make sure used parts are good before installing, and make sure all of the parts are compatible). The FTP is relatively easy, if you are only doing that. You do have to drop the column to get at the parts.
The FW column and 92 or later columns have a stud with a nut head on it holding the ignition switches when you remove the nut for the FTP switch. The 91 columns do not have the "push brake to shift", and the switches are easy to move when you loosen the screws, because it does not have the stud. The nuts and bolts on the column are a mixture of 7mm, 1/4 inch, and I believe 3/8 inch.
Lynol...those people come down here from up north, and think they are still in Conn. You need a reverse printed sign/tint on your front windshield that says "the gas pedal is on the right". They probably would not understand that either.
