I don't know all of your options, you might want to call Curtis at Wild Steed Worx 619-823-8557 he carries Electronik's EHC Controller by Axel but I think it's only compatible with OEM wiring Harness which he has access. Curtis can give you some options. I have Electronik's EHC with new charging system (VR, rotor & stator) about the last 2 years with no problems.
