I don't think you want to run hot exhaust into hose before injecting the 
water.  And I'd think you'd want the muffler relatively close to the 
engine.  Mine is in the port cockpit locker.

It sounds like you're talking about the voltage-regulator sense wire. 
 This definitely needs to be connected, or the alternator won't work so 
well.

The alternator output does normally run to the ammeter on the engine 
control panel and back.  It's not such a great setup.  You can get 
ammeters that use an external shunt placed close to the battery.
