What starter solinoid do I need?

[signsup]

So if I use the solinoid pictured above with the three posts, presume post 3 from battery is the positive battery cable? Post 1 goes to starter, the solinoid itself is not grounded externally by mounting to firewall, and post 2 is a lead to the starter button on the dash. All other electrical would work as currently installed? This seems like a simple set up to accomplish and would give me my desired effect of a military on/off switch and the starter dash button. Still tracking two wires from current solinoid set up, one is single wire to keyed ignition but other enters a loom with other wiring harness wires and will need som volt meter work to ID. Any thoughts on what a second wire from the same post as the keyed ignition start wire would be? I cannot think of another item that would only be energized during the start position. I could remove one at a time and see what stops working, I suppose.

Yes

Yes except the extra wire, probably the green

That's what I was thinking too! Check the green and purple for voltage with the ignition switch on and off, then again with the key held in the "start" position, also check for continuity to ground for each.
