I think methodically listing all components that require and/or would work better from the Rhino harness is step 1. Then work in all of one's wants/desires to add in is step 2. Step 3 is marrying them together with the Canam accessory harness. The other Canam harness is left untouched as it's for engine only pretty much.
Step 1 - (Sitting at work trying to remember everything is the pits)...To start out the list for the Rhino harness is: headlight switch, both plugs for the front diff, 12 V acc plug (I left mine on both harnesses), brake light switch, headlights, necessary relays, emergency brake, fuel tank sending unit, taillights. There's a start - maybe other swappers can add to it what I missed.
Extra wiring put in for: UEGO gauge, water temp gauge, future whip, future reverse lights, future backup camera instead of mirrors, and other accessories one would want could be added.
Here's the tip of the day tho::::since the Rhino fuse block didn't get used in the main system, I left the wires from it as long as possible and used it for an accessory block. I had 7 fused circuits to do whatever with. I wired up 5 to 12 V hot and 2 to 12 V ignition. Let Painless keep theirs, you have your own for $0.00.
I put up pics in my PB acct of the before/after harness morphing, but they are not useful for reference IMO......LBR
