CooleThanEthan,

Good troubleshooting. There should either be two wires on the coil side of the ballast resistor, or two wires on the + side of the coil. The ignition wants to see a full 12 volts on START.

Your correct on the firing order, 153624. The cylinders are numbered from front to back, but there is no arbitrary position on the distributor cap for plug #1. It can be anywhere, and is dependent on who set it up. If the truck ran before, and nothing was changed, it should run again.

There is a simple procedure to find TDC on cylinder #1 and position the distributor and #1 plug position to match it...but it isn't necessary. Your 'no spark' problem is different than a timing issue. If you get spark and it runs, you are home free. If you get spark and it exhibits timing problems, address it then.
