Default General therory on boat wiring? In particular '97 Baja 272

Is there any standard on boat wiring such as like on a house were everything has a standard flow chart? The wiring on my 20 year old Baja is at its end with a lot of stuff not working such as running lights and my gauges are rather twitchy. From what I can tell all of the power for the boat comes off of the canon plug through the engine via barely adequate wires, through a fuse box, and then to the switches to be distributed out.

Does someone make a fuse/circuit box with an integral relay? I'd like to have a dedicated relay fuse box in the engine compartment to run the bilge equipment and another one up front to power the accessories etc.

Stock MPI is long gone and just have a carbed crate engine.

TIA!

There are some color code standards.
I ended up building my harness from scratch. Not a big deal. I used poly spiral wrap to harness up all the conductors and installed whatever terms each conductor needed.

What was your general flow? Key switched relay>fuse box>switches>out? I like the idea of one big relay to a fuse box but I'm not really finding that as a general method on boats.

I had success with cleaning up and tightening the connections at the fuse panel on my Baja. Restored voltage loss I was seeing on the gauge and corrected a few flukey problems.

Nice, sounds like a good winter project for me.

I'm suprised Painless Co. doesn't make harness' for boats yet.
