Mounted the starter contactor using one of the battery box mounts and shimmed the lower bolt hole which goes through a reinforcement angle. Connected the two with a brass bar.
Mounted the ANL current limiters next to the battery box and above the starter contactor. I can reach these from the bottom of the cowl, if I ever need to. Power will come from the unswitched side of the starter contactor, the post connected to the battery contactor. Both share the hot side with a brass bar.
Mounted the shunts as seen here. The current draw is measured across the two posts on each shunt.
