That's an awful small engine.... 
The aux power control connector is the "Power Point" socket in the dash. You actually shouldn't rule out the clutch switch, because the wire harness to it is there in all the trucks; the automatics just have a jumper plug in place of the switch. So that jumper may be shorting something, so it'd be good to disconnect it as part of the diagnostic. Not sure about the shift lock actuator; if I don't forget, I'll check my EVTM tonight.
(And see if you can fix your SHIFT and PERIOD keys; this isn't chat or txt, this forum will be here forever....)

The clutch switch connector is to the right of the brake pedal; that's where the pushrod is on a manual truck. On an automatic, I don't know if that connector / jumper would be just hanging around there, or if it's maybe zip-tied to the brake pedal bracket or something. It's a long skinny connector with four wires in it.
