This is my friend Tony's chopper. The bike ran with this wad of wires stuffed behind the battery tray. It was all pretty sketchy and lots of unused extra wires present. It seems to be the complete Buell wiring harness rolled into a ball and electrical taped together.
Even had an extra harness zip tied to the left front down tube. the only thing that came out the bottom was the turn signal wires for the front. There were also some connections tied together that led back to the ignition module.
I have a service manual on the way to sort out the ignition system and get the bike to a bare minimum of wiring. I'm also going to add in some connectors for the handlebars and headlight.
