Hall-Effect Foot Pedal Throttle

[sguo]

Hi,all;
I was planning in using Hall-Effect Foot Pedal Throttle from http://www.electricscooterparts.com/throttles.html, but it was with 3 wire terminals. For those used in golf cart are actually 4 terminals. I called them and they said that it fits their motor controller. Could anyone let me know the difference and if I could fit it in the design with 4 terminals? Has anyone utilized this type of pedal in electric go kart?

What controller do you have?

Curtis controller

The one I have now is Curtis 1206, but I am thinking to have Alltrax programmable 300A. The current setup for Curtis 1206 is with 4-terminal connection (picture).
