Looks like the clutch safety switch.......jacked the clutch pedal up and down a few times and fired right up. From what I can find, they are pricey little parts....$300 to $400 ..Yikes. May just ground it.
Ground it. I pull those when they go bad and just ground wire to bolt mounting of relay on fender. Just start in neutral, smartest thing to do. Try rebuilding it, its possible.
