I am going by memory at this point but here goes. I had the same problem with trying to use the column switch with no success when I went with a 460 trans, found out there are 2 different style 460 trans, one uses a switch that mounts to the trans shifter shaft the other does not. My trans came out of a 2002 trans am and it did not use this type of switch BUT the only difference is the length of the shifter shaft between the 2-style trans. So, I bought the longer gm shaft and replaced it and then I could use the GM switch. If you search my old threads all this info is in there. It is easy to change the shaft. The wiring was easy and now I have back up lights and neutral safety lock out.
