Boat Wiring

I have seen many post about wiring diagrams for boats, I hope this is a help. Thanks to Max at www.outdoor-links.com



Boat Wiring Color Codes



Wire should be marine grade, multi-strand and tinned. Tinning will drastically reduce, corrosion and tarnish. Do not use solid strand wire. The constant vibrations and movement will cause the strand to break.



This list is of the most commonly used wire codes used in boats today.







Purple - Ignltion switch controlled



Green - Bonding



Yellow - Alternator AC and field



Red - Unprotected battery wire



Black - Grounds



Brown - Alternator starter to ignition



Orange - Alternator DC output and accessories



Gray - Tachometer



Tan - Water temperature



Light Blue - Oil pressure



Green/White - Engine trim in and or tilt down



Green/Orange - Engine independent trim down



Blue/White - Engine trim out and/or tilt up



Blue/Orange - Engine independent tilt up



White - Not for less than 50 volts



Yellow/Red - Starting circuit



Yellow/Black - Choke



Black/Yellow - Ignition stop



Brown/White - Trim position sender
