Have posted a wire chart .
To work out the amp draw of say the lights etc use the formula that Watts = volts x amps
Example 100 watt light would draw approx 8.5 amps in a 12volt system .
Ignition draws 4 amps
Generator may charge 40 amps
By working out the amp draw you will be able to select the correct size wire .
All the best
