One Wire Alternator Install

Has anyone done a conversion from external regulator to a one wire alternator? Have a diagram? Thanks.

When I did my Powere Master I just took the big redwire to the one terminal and taped off the grey plug in connector. I removed my regulator and most of associated wiring. Your idiot light will not work anymore.
