You'll find it handy to have negative buss bars in both the stern and at instrument panel. In the stern you'll attach the negative engine cable and both battery cables, along with grounds for bilge pump, trim tabs and stern light. And IP - buss will have grounds for instruments, lights, VHF, and other accessories like DS, GPS, and maybe a 12V cigarette lighter outlet. It's 10' from transom to bulkhead so you'll probably want to run at least 10ga or heavier wires from battery to + fuse/circuit breaker panel & - buss bar at IP to insure low voltage drop. I'd run the engine harnesses (ignition harness to control box and engine data backbone cable) first because the Deutch connector plugs on the ends take up a lot of space in a 2" PVC conduit, although they'll be outside the conduit once installed. (I didn't do that and had to take the connectors apart, tape all the wires together and then reassemble after getting wires thru the conduit and rigging tubes! Would have saved a lot of time if I"d run them first!)Then the other wiring will be easy to run. I used a polypropylene line left in the conduit to run future wires; that type of line acts like a Chinese finger trap when you put tension on it, so it grabs on to any wires you put inside it.
