Hi Kingy, not sure on the green wire, only wire that goes to the starter is the heavy wire from the solonoid. The ignition switch could have 2 on positions, first on is on which doesn't interest you unless you have an hour meter fitted, and the second position is spring loaded and this is the wire that goes back to the solonoid to trigger the solonoid shut to crank the motor. The red wire in the black sheaf can either go to the battery side of the solonoid or directly to the positive terminal on the battery. Once you hook this wire up check that it is charging with a multimeter with the motor running
