1985 class a electrical wiring

Here goes. New to rving. I was given an 1985 honey 27'. P30 chassis with 454 engine. They were having a battery draining issue and got tired of trying to figure it out, good news for me. They decided to connect everything to 1 battery, I am connecting it to 2 a starter and house both 12v batteries. I am trying to figure which wires go where. In tracing the wires I found something that seems wierd to me. I have 2 isolators on firewall. In drawings I have seen on starter battery connected to one side and starter on the other with the middle connection going to alternator. Mine has the middle running to the ignition switch and spliced to a pink line that goes thru engine harness and connects to distributor. Does the line running from middle connection belong connected to ignition switch or should that go alternator? The other isolator is connected to emergency button on dash. Does the line running from middle connection belong connected to ignition switch or should that go to alternator? I have pics if needed.

I think I answered this on your initial post.

Many have this going to the ignition switch or some other 12vdc supply that is only on when the engine is on.
