hi you can use any controller from ebay etc for your motor 36v 48v if you got battery of same volts. all connections are usually the same but if it does not work correctly first time then turning around the hall and phase wires will get it working. phase wires are the three thick wires blue yellow and green. hall wires ere the five wires in the smaller plug. red black blue green and yellow. connecting to your motor as is may not work right away but some wire rearranging will get it going. their are 36 combinations i think. ask if you need more help cheers.
