1967 Mustang coil resistance wire, external resistor problem.

I am putting a 1967 Mustang back together for a friend. It has a 289 and no coil. I bought a replacement coil and it indicates it needs a "resistance wire" or an external resistor. I cannot find a resistance wire or an external resistor (proceline ballast?). There are two wires where the coil was attached. One goes directly to the distibutor and the other goes to a three prong connector and from there through the firewall. The wire that goes to the connector looks like an ordinary wire and not any type of special "resistance wire". NAPA shows a special resistance wire for this car.

What am I missing here and how should this be hooked up properly?

Your resistor wire (pink wire) is located in the under dash wiring harness. If you have the correct coil you already have what you need, if everything is original.

Dare to be DIFFERENT. Stay INLINE

X2 Wire should be in place. It is 60" long, 1.4 ohm resistance. Connected to the run side of ignition switch lowering voltage for the stock coil. If by chance it has been removed, a 1.4 ohm ballast resistor can be wired in. Here is a pic of the wire and schematic for a 66, but it'll be the same. Wire #16a, color pink.
