1--Use a 4 terminal disconnect, properly known as a "double pole single throw" or DPST switch

2--I see no reason to use Ford solenoids. This adds more (contact) voltage drop in the starter circuit.

Run the alternator directly to the starter relay with a nice big, say, no6 wire. Jumper the starter relay to the starter terminal. Run your battery cable from the starter post to the trunk, or use a font mount junction point to relieve cable stress off the starter

Run two no 14 wires from engine bay to the rear and hook them to the disconnect small terminals

Run the disconnect in series with the main battery cable

Hook the two no 14's to the disconnect small terminals

Up front, pick one of the no 14's, and run it to the dark blue "run" wire out of the bulkhead -- or whatever you are using for "switched ignition."

If you are running MSD hook the second no 14 coming back up from the disconnect to the "small red" MSD wire

If you run "other" ignition, use the no 14 to key a good quality relay, and use the relay to power your ignition system. Properly fuse

No other solenoids, relays, needed.

In my opinion, running the alternator wire back to the battery + does NOT MEET the intent of the rules, because with the battery shut off, it leaves a hot lead coming up from the battery
