1979 Ford Bronco Ignition

Hello Ford Fans, Recently Someone abandoned a 1979 Bronco in the woods on my property. The body is in sad shape but it was running and 4wd functional when left here. The local police want nothing to do with it and told me since its on my property I could do whatever I wanted with it. It is beyond road worthy but would make a good plow truck. While they left the truck they took the key!!! How do I hotwire this thing. I tried running a + lead to the coil and crossing the leads on that whatyamacallit next to the battery. that resulted in the engine cranking but no spark from the coil to distributor. someone suggested there are modules that also need current. also suggested the best way would be to hotwire the ignition switch itself. ANY HELP ON WHICH WIRES TO CROSS? It won't be long before the local vandals find it!!! help

Here's what the wiring should look like to the ignition module.

Thank you for your quick reply. schematics is what I was told to look for but alas electrical diagrams are not my strong suit. any other replys designed for a simpleton would also be appreciated. I will study this diagram and see if I can translate it. Thank you

Anti, do what you did the first time, and in addition run a 12v jumper to the red wire going to the ignition module. This should give it some spark.

Is this going to be a long term solution? You really need that resistor shown in the diagram, and it's made into the harness from the original ignition switch.

Thank You both for your help it is greatly appreciated. I will give the lone rangers advice a try. As for long term usage, my first priority is to see how this truck runs and get it closer to my home. After determining its servicability I can replace the ignition switch. It may also be possible to jump the wires at the back of the switch, any thoughts on this? Once again Thanks

Sorry to say, still no spark. The rotor spins so the timing chain is still in one piece. Either the coil or ignition module is shot or there are other connections that are needed to be made. Any specific ideas on how to jump the ignition switch itself.
