Pontiac dumped the working shaker option for 1973 and gave a $ credit back on T/A window stickers, but I guess they still used the same dual purpose kickdown switch.

Mine is a first week of June '73 car, auto. It would be interesting to learn how this affects the voltage to the solenoid. I recall trouble shooting mine at one point and the flapper (I have a conversion) was opening intermittently and some times late. I noticed that the solder had come lose, but I also opened it up the case and cleaned it up a little and put 'er back in service.
