Whoa...lots of discussion.

By default the kickdown has a red/orange set of wires running between the 12v source, to the switch, and then down to the terminal on the driver's side of the case for the detent solenoid.

The billet box Lokar provides has a tiny actuating switch inside the box. One side is the 12v source while the other side runs to the terminal.

To test the existing soleniod in your transmission you'll have to have power to it at or just before WOT.

Also, you don't have to mount this Lokar switch under your transmission pan. I found that there are two holes in the frame channel on the driver's side just next to the transmission that lined up PERFECTLY with the switch, so I mounted it there up inside the frame. Also you'll have to adjust the set screw on the cable a few times to get it right. You should hear the switch click closed right when your carburetor is nearing WOT by sliding back the accelerator rod and listening for the "click".

Have fun....
