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.
