Les...Make this a sticky, we get enough questions regarding wiring.
Here are the standard wire colors used in the boating industry since the late 70s. When re-powering a boat with a newer motor this is a handy reference. Most boats use these standards but always double check in case changes have been made.
Black----All Grounds
Black with Yellow stripe---Magneto/short to Kill
Gray---Tachometer signal
Yellow with Black stripe----Choke
Red---Unprotected(12V+)from battery
Red with Purple stripe---Protected(+12V)from battery
Purple---(+12V)from ignition switch
Tan---Overheat sensor to warning horn
Pink---ending unit to fuel guage
Yellow with Red stripe---Ignition switch to starter solenoid
Yellow---charging stator to rectifier
Lt.Blue with White stripe---Trim up
Green with White stripe---Trim down
Some more standard wire colors used on many inboard boats, always double check though, as some vary or may have been changed along the way!
Some standard colors for boats since 1980 are as follows:
В· heavy red 10 guage (main battery)
В· heavy black (main ground)
В· purple (ignition)
В· yellow (starter solonoid)
В· grey (tachometer)
В· brown (temperature)
В· blue (oil pressure)
В· brown with stripe (alarm)
Accesories
В· pink (fuel sending unit)
В· yellow (blower)
В· brown (bilge pump)
В· grey (navigation lights)
В· heavy green (bonding wire)
В· red (misc electrical add-ons , vhf , depth finder, stereo, radar, power supplies)
. medium blue in harness (gauge lights)
