I recently acquired a 72 cb750 with all kinds of crazy wiring. So I pulled the harness, and will install a new one. I currently don’t have any gauges, horn, or turn signals. It is also with out any fuses. I’m very new to this bike and im looking at switching to a lithium battery so I can hide all my wires under the seat. Any suggestions on batteries and also, do I need fuses if im running so little electrical items. Not sure what the terminology is here. Any ideas or help would be greatly appreciated
