Bf250 main harness plugs

[Lmoore87]

Trying to figure out what all the plugs are for on the main harness ignition/kill switch side. I have a couple plugs with cut wires and one plug with 3wires that has but splices and all black wires coming out of the splices. Assuming those went to a ground block but not sure about the other plugs.

I've attached a diagram of how these are all connected. It's for a dual engine setup, but you should be able to figure it out for a single engine. These are for digital gauges.

Thank you for the reply. I’m unable to open the attachment on my phone but I’ll try when able to get to a computer. I also found a yellow cable missing from the front top of the fuse box. It’s in between a red and green cable and the bolt was loose so I feel like something was there also but so far no luck on google being able to see where the other end of it goes.

Im needing a wiring diagram of the actual key switch if you have one. Thanks

What controls are you using. Key switches are the same for all the efi Hondas?

Top mount controls. I bought the engines used and they didn’t come with wiring harnesses. I now have the engines to helm harnesses for both engins. I need gauge and key switch harnesses. I think they take two or maybe three more harnesses per engine per the diagram i have but it doesn’t have diagram for key switch wires just shows switch panel.

You've lost me. What you need is a standard honda dual ignition switch assembly, it will plug into the engine harnesses direct, and then you need to buy 2 gauge harnesses . The dual ignition panel comes with the harness to plug into port and stbd engines
