I just finished setting up my 1000-5 LE. See if this helps/works.
Winch: battery pos. to winch mechanical breaker in plastic box to winch solenoid bolted near back driver's side. Wired out for controls.
All Acc: battery pos. to 30A circuit breaker (attached to pass. side near air box) to relay (key-on-power from positap on acc fuse) to 6 slot fuse box with neg. bus. fixed near back passenger side.
My Acc: fuse box has one slot left free. The others are 1) winch, 2) wireless remote, 3) street legal signals, 4) horn, and 5) 4" LED round lights on a relay.
Note: I left the main and winch power cables long and the dual battery area open (with room up front by refill tanks for the dual batt. isolator).

PS: Just saw Rubin's post. His has one of the six tap fuse boxes I'm talking about. I mounted mine upright against passenger side near the back of the compartment - it looks like his winch gear is near where I put my fuse box. There are many ways to do it, but do spend a lot more time planning (including for expansion) rather than cutting and bolting.
Ground battery to the factory ground on the engine. Get a voltage sensitive relay module so you can charge both batterys . i used the ground under the hood that Honda gives you to ground my fuse pannel and winch. Just take your time.I even kept the stock air intake because I had the room to do so.
