All you have to do to hotwire one of these is run a "hot wire" from the battery to the coil, and jump from the battery wire lug to the solenoid lug on the starter. Don't want to run it very long this way, though, because the normal battery-to-coil wire will have a resistor in it to prolong points lifetime.
If I were doing this, I would do these steps:
1) Make sure the engine isn't seized.
2) Make sure the engine is getting good gas -- temporarily run a line to a 5 gallon gas tank works.
3) Make sure the fuel pump is working and the carb isn't stuck -- turn it over a bit with the pedal pressed and check for gas smell.
4) Make sure that, with the engine in the "ready to start" position, you have 12 volts measured at the coil.
5) Start it up and drive it across the country.
You can check underneath, but if the body isn't shot and the truck hasn't been stored in tall grass, the frame is probably in good shape.

P.S. Joking about #5. Drive AROUND the country!!
