Nope it's neither one of those.

The one that mounts on the gas pedal bracket is wicked simple.

Looks like this:

So all I need is that switch?

What's wrong now? Why are you ASSUMING it's the switch? Do you know which switch it is? I'd hate to see spend the cash and that's not the issue. How you checked the wire to make sure it's connected? Are you sure you've got power to the kickdown switch at the pedal? This could just as easily be the wire slipped off in the trans pan, or the solenoid inside the pan has gone bad too.

So tell all. Was it working fine, then all of a sudden you notice it don't work? Recent trans swap? Any other electrical issue recently?
