As I am asking, with a one wire alternator going into a boat originally wired for a 3 wire and upgrading to a 105amp,

should I run a new power wire to the battery separate from the original wiring harness ?

what exactly are the Orange, Purple, and Black wires for and where do they hook into ?

can I just leave these unhooked or do I need to wire it any differently that it was the last 3 years with only the orange wire hooked in ?

any help with these questions is much appreciated.

someone spoke with Indmar and they were told to bypass all the original alt wiring and ran a new wire past the breaker and to the starter, not the battery like I was thinking.

just thought of another thing.

If I later add an isolator for a dual battery setup where does the alt. wire need to come from that connects to that ?

Clint - it depends how big your stock wires are. You will need 4ga or bigger to get enough current to your battery and accessories but if your batteries are more than a few feet away you will need to increase the wire size to 0 or 2 ott. There should be a circuit breaker in your engine compartment that will need to be upgraded as well.
