Ignition Problem

[bcoke]

I pulled the switch and didn't look like anything was burned up or malfunctioning. It's hard to tell from the picture but it actually looks fairly new. Is there any way to tell if it's bad or do i just have to replace it and see?

It's hard to find the problem by chasing the wires to check down stream because the other picture is what it looks like under the steering wheel... the wires all look good themselves but it's a bird's nest

Does anyone know which of those wires in the first switch picture is the hot wire that is failing to make contact when i let the key snap back?

And dumb question: where in the engine bay is the starter solenoid? Is it on the starter motor? I'm trying to trace the wire from the switch all the way through to find problems elsewhere in the circuit
