Jim,
You replacing all the wiring or just repairing as needed?
If your replaceing then you can do as you want.
The only real color codes would be for the engines.
Standard for house would be red/black for dc and green/white/black for ac.
Blue is oil pressure.
tan for water temp.
gray for tach
black for ground
red for dc feed
yellow/red stripe for start circuit
purple for ignition feed
Alarm circuits I've seen a few colors but are usualy brown/white stripe or tan/white stripe.

A good part of the old bertram dc wiring was just white everywhere. Some had numbers, some did not.

I have the schematics for a 28. I'm sure there's not much difference in a 31. Email me at
ejcurry@verizon.net and I'll send you the file.
