I have a 2022 BF225. I cant figure out what wires light up the tach and the Fuel gauge. there is 3 blacks and a red hooked up and a few ringed terminals in that area that are just hanging. Its a mess of spaghetti back there. Its super tight squeeze under the helm and Im a big ol fat guy. I cant seem to find a wire diagram either. Any suggestions. Its on my 2022 22'Northriver. I took it back to the dealer for its 100hr service and asked them to fix it. They didn't and I didn't check before I drove off. The dealer is and hour away. Trying to fix it myself.
 
Hi,
Not sure if this would help you but the official Honda Publications lnk below is where you could order the "real deal" shop manual. It would contain the wiring diagrams for the outboard and if the boat manufacturer used the same wire color code, you maybe could figure the instrument lighting out.

Also, I see that they offer some "Free Downloads" for the big V-6 outboards and there's wiring diagrams listed under that heading too.

Good luck.
 
Try this diagram. It's for a twin engine setup, but you can easily figure it out for single engine. This is for the digital gauges.

I had a mobile guy come out and look at it. Apparently the factory wired it wrong. They never ran a hot to the light. He said usually they they tie it into the Nav light switch. He fixed it. Thanks for the replys.
 
Glad you found someone to help you and that you got it sorted out.

Thanks for updating and explaining what you found.

Happy and safe boating to ye!
