Wiring

[C YENSEN]

Anyone have a simple wiring diagram for a mid 80s? Specifically wires on back of instrument panel.....

from my best recollection for most domestic engine wiring
Red= 12 volt constant
Black= 12 volt ground
purple=key on 12 volts
yellow/red stripe= starter circuit
Tan= temp
Tan/blue stripe= alarm circuit
light blue=oil pressure
light brown=trim
gray=tach signal
green = hull ground
black/yellow stripe=stop circuit on outboards
purple/white stripe and sometime black/white stripe=choke or enricher
light blue/white stripe(sometimes just light blue) trim up
green/white stripe(sometimes just green) trim down
purple/white stripe=trailer trim
Yamaha/Suzuki/Honda all have their own colors
hull wise, normally i see pumps all dark brown with colored stripes for more than one pump(each pump gets its on color stripe)
lights are generally gray, with stripes for multiple lights

This one is pretty generic, First one i found using search
Some one has a black and white one that is more specific to the V20

It’s on here somewhere

Edit:
Found it
Look in the links section 5th topic down
