The only connections from the Redarc Smart Start Battery Isolator with Wiring Kit # 331-SBI12KIT to your start and auxiliary batteries are the positive posts. This kit comes with enough wiring to reach from one to the next so you won't be connecting the exciter wire from your alternator to this system.

You'll want to connect this isolator per the diagram I'm linking a photo of.
