Hi John,
I was doing the same with the ezee throttles but found that it is very easy to damage the hall throttle by connecting incorrectly (as I did) so I have ordered a new throttle from ecrazyman and this will have same wire colours as the controller (still waiting for it to arrive so not sure if it will do the trick).
The wires from the ezee throttle and out of the battery monitor that go to the controller are coloured white, green, blue. For the ezee controller to work you also need the yellow connected (don't know why). So I guess that the white green and blue should be connected to the controller 3 throttle wires but not sure which wire goes to which colour (sorry).
