Not sure if it is really the right/best solution... But what I have done on my motorcycle(and possibly plan on doing on my Super) is to use these normal elctrical 'blocks' (electrical connectors) like these:
I have a main power wire comming in on the first connector, and then a 'link-wire' that goes to every second connector. A common negative that comes in on the second connector, and then to every second connector as well. This way, I have a few terminals available. If you do choose to do something similar, please remember to fuse every wire that comes from this block, and make sure that you dont overload the initial (+) and (-) wires!!!
Hope this helps.
