I remember seeing a red or orange looking wire going into the CDI. Tried to trace it back just by observation and couldn't find the other end. It was cold in the shop and fresh-baked chocolate cookies were calling.
I have a wiring diagram but I noticed some inconsistencies with my harness and what's on the diagram. I don't know if it's allowable to post that diagram - read the concerns from the mods about posting service manuals.
