Attention: TDR Forum Junkies 
I used a Murray 35720 to replace the stock cycling switch on my 1990 1st Gen.
It uses a dual mounting bracket that has the same dimensions as the original OEM unit, so it bolts right up to the original bracket if you like. I relocated mine however, so I could access to the pressure switch behind it in the future if need be.
The Murray unit is also adjustable. The factory settings are 44 degrees "ON", and "30" degrees OFF, which worked fine with me.
For pictures and more information, follow the link below, which will take you to my install thread.
