I'll give ya the before and after. I have already made some of the "before" parts too.
Before
Tie wrap batt connector to seat rails
Mount switch to batt rack
Mount terminal block to bike frame with bracket
After
Remove handle from batt box and screw batt connector to top of box.
Mount switch and terminal block to batt rack
Simple & elegant
Stupid me was trying to save removing the rack one more time. And mounting that big connector to the top of the battery where that handle is was sheer genius.
Sometimes it pays to work slow -
