Get a voltmeter; it's cheaper than any other part you'll be troubleshooting at this point; troubleshooting without it has already gotten expensive (the starter relay might have been fine) and will get moreso. You need to test for voltage at that ^^^^^ wire while an assistant holds the key in the START position. If no voltage, check at the clutch switch bypass, key in START. Continue following "upstream".

Have you confirmed that your bypass for the clutch switch is still in place?
I was going to grab one when I go out shortly. There was no doubt the parts I already replaced were bad. Hell, the ignition switch was burnt to a crisp on the inside. xD I did check the bypass is still in one piece. Thanks for clarifying that wire. I'll check it out.
