The later didn't have the resistor, but have heard time and time again of the purple wire issues.

The purple wire either fails because the solenoid is taking too many amps to kick the starter in. Or because it comes in contact with the exhaust manifold because someone changed it's route when they were working on the starter.
This lavender/purple wire in his photos is the resistor by pass wire. That should fasten to the stud on the stomp pedal switch.It may run up into the cab and back out though the gromet,
1 diagram that I found for 59 GMC six cylinder wiring said that wire should be yellow. That one didn't have the rest of the wiring from the switch so I didn't use it.
