I think that you would use split wire loom. Ebay lists 177 choices. See: http://cgi.ebay.com/ebaymotors/Wire...mQQcategoryZ46101QQitemZ8025600832QQrdZ1
I would think that you pull it from the mast butt to the head. It sounds sweet.

Don't forget the rubber grommet to protect the wire as it passes through the mast cap.
