The dealer installed the connection for me on my H26 with the same motor. While I haven’t used it yet…He wired the plug directly to the battery switch, so you could charge one or the other batteries – or both.A word of caution, with the connector wired and not attached to the motor, that gives you a live current where it’s wet and near the fuel tank. I put a different wire “thru-hull” in so that I can push the excess wire from the connector back in when not in use. Also, you will want to know which is positive of course before connecting.
