And save your self some money, if that kit includes a suppression diode and pre-charge resistor, it is a waste as you do not use it on the current XCT line as it is all handled internally through the controller for its own protection. You should get a Regen Diode (6 amp) to be installed on the large post to protect the controller from a regenerative current surge.
A good source/supplier is going to tell you that and the thing about ours here is they "will" program it for you so when you take it out the box and install it, you will have a performance tuned controller to your specific application with the appropriate map installed.
