just wire a simple relay off a keyed power lead to a relay to switch the optional ground disconnect so you do not have to remember to flip to switch for the acr

I wired mine like your diagram except since I have twins I put a Bridge Rectifier to separate the ignition switches. I ordered them from Digi-Key as per Blue Seas recommendation.

I buy from Digikey half a dozen times a year. Delivery speed is amazing.

^Looks like it would work perfectly for me. But north of $900 is a wee bit rich for hobby level guy.
