Wiring to connect the starter relay

Connection to the neutral switch:

I've chosen to use a 6 mm ring terminal instead of a 5 mm ring terminal on the black wire. Originally the neutral switch provided the ground for the starter relay, requiring the transmission to be in neutral for the motorcycle to be started. Since so many people permanently ground the starter relay using a 6 mm bolt on the transmission, I've decided to simply provide the 6 mm ring terminal. Should you desire the original 5 mm ring terminal, I will be happy to oblige.

Magneti Marelli starter note:

Early Magneti Marelli starters required a separate ground wire. The modern replacement solenoid also requires a separate ground wire. Given the inconsistent need for a ground wire, I've included one with all the Magneti Marelli sub-harnesses, just to be sure you have everything you need.

Alternator note:

With the original Magneti Marelli and Bosch charging systems, an unfused wire was run from the voltage regulator to the starter relay. Since the voltage regulator for the alternator is integrated into the altnerator itself, another means of providing power to the starter relay is required. This sub-harness includes a separate wire that connects the battery positive terminal to the starter relay. The length of this wire is 350 mm and a 6 mm ring terminal is provided for the connection to the battery. This should work for just about any battery / starter relay installation.
