This is an easy one.
Go to an auto wrecker (preferably a u-pick type), and find a mid to late 70's ford pick up with a 390 or 360. Pull the distribuer out along with the coil. On the left side inner fender there will be a square silver ignition module. Take this as well. Now, carefully remove the wire harness. This wiring is all connected together except for two wires that come out of the module. These wires can be spliced together and hooked up to your old coil positive wire. The rest of the harness just hooks up the same way it came out. This is why I keep the coil as it has the proper pins that accept the harness. Good luck
