Bob, I'm no expert but I'm learning all the time. I too don't see a need to replace the old wiring if it's working. Sounds like the port locker is the place for the batteries. At least I don't have to move all the existing wiring and charger.
Funny thing about the sea cocks. Most things I've read say to use 2 hose clamps per connection. I plan to. But nothing about safety wire. I used to road race motorcycles and we would wire every hose clamp & put one on the spin on oil filter to wire it to something solid. Seemed to work pretty well & would add another layer of protection to the system. If the clamp broke the wire would keep tension around the hose. Steve Huber Judy K II C27 #3810 Long Beach, CA
