Ruff and Tuff controller

Has anyone replaced their controller on a Ruff and Tuff? I have a 2008 Hunter. I would think that other 48 volt controllers would work. Maybe custom from D&D or Alltrax.

Same here as im doing a conversion with Alltrax SR48500. Problem is wiring on RT is different from EZGO. The throttle thats in it is a 3 wire, not sure why? Needs 5v coming into it and 5v going out, have had a hard time finding info.
