Need confirmation of correct starter wire for ACR

Hi all, I'm installing a Blue Sea ACR in my boat and one of the features is a starter isolation circuit. To use the isolation feature, I have to connect a terminal on the ACR to a positive line on either the the starter switch itself (which I'd rather avoid because of the length of the wire run) or to a positive connection on the starter solenoid that is only active when the when the starter is cranking. (If the isolation circuit is connected to a positive line that stays active while the engine is running, the isolation circuit won't work.)

I've been reviewing a trouble-shooting guide for the starting system created by Don S. (http://forums.iboats.com/forum/engi...hooting-your-engines-starting-system?t=167035), but I wanted to get confirmation that I've identified the correct circuit before I wire things up. If I'm interpreting the starting system diagram (below) correctly, I think I want to connect the start isolation circuit on the ACR to the "yellow/re 7" wire where it connects to the solenoid at the "C" terminal (in the solenoid diagram below). It looks like that line would be positive ONLY when the key is in the start position.

Have I got this figured out correctly?

Thanks!

Jim

Ayuh,.... Both B, 'b C are 12v on the slave solenoid, only with the key in the start position,.....

Both of the tiny terminals on the starters solenoid are 12v, when the starter is cranking,....
