Check the neutral safety switch. And many times a truck has had a automatic, and has been switched to a manual. So there is no neutral safety, so that breaks the circuit and it won't start. You will be looking for the red/blue stripe wires.

What happened to the original harness and the original components on this truck? It already had all this. It had a ECM relay which was powered from a white/lightblue coming from the ignition switch. This should all be out under the hood. Look on page 60 in this link.

I have the original harness, but its a rat's nest of bare and faded wires and broken connectors. Per page 60, a white and light blue wire should be hot at both positions of the key...page 29 has it starting out as different colors...just having a hard time finding that one wire (or group of) as the w/lb wires I've tested so far are hot in run only which means either I haven't found the right one or a connection is missing somewhere to the ones I have found. Nevertheless, that looks to be what I need.

There you go, keep staring at those diagrams. It's tough at first but gets easier and easier. You will be a expert pretty soon. You need to be to keep this old truck running. I would have thought you would have access to a Ford Motorsports wiring diagram for the harness you bought? Instructions of some sort? It bet it's made for Mustangs isn't it?
