Which brake light switch?

For those who are running electronic transmissions- Which brake light switch did you use? What did it come on orginally? I need to go get one tomorrow but need to know what make/model it orginally goes on.
Thanks!

80's GM trucks have a cruise control / brake light switch that works great because it is normally closed on the cruise side, so you can interrupt the 12v signal to the 700r4 when you hit the brakes. If you find the p/n somewhere you can get them at the parts store cheap.
