I think more on the wiring side of the 20v conv. would be very beneficial, particulary, alternator wiring, and making your circuit opening relay. As these are most likely the most difficult part of the conversion for someone new to conversions.
also step by step conv. guides for the more common of conversions, would be good a there is no true how to guides about.
if u need a hand with anything, i'm more than happy to help
