Stock curtis 300amp controller to Alltrax SR controller for a 94 club car ds
 

I have a 94 club car ds with a stock curtis 300amp controller. I recently purchased a alltrax sr 500 amp controller and need help wiring it. I'm pretty sure about how to wires to the B+ B- and M- I just need some help with the other six smaller wires. three are connected to "1" "2" and "3" and the other few are coming from the on board computer and look to be connected to B-. if someone knows where or how to wire the alltrax I would greatly appreciate it. I do have the appropriate solenoid installed and have a larger motor coming as well. I have pictures of the current controller installed if that would help.
