That is a very cheap and easy fix. The wire that goes to the + side of the coil is part of the engine gauge harness, which costs like 35 bucks, and the wire that goes to the - side of the coil is called the distributor primary wire and costs about 5 bucks. Replacing the engine gauge harness is a very simple matter. Just unplug the old one at the firewall, the heater blower, the starter solenoid, and the sending units, and plug the new one in.
Yup, replacing the engine gauge harness can easily be done in nearly no time flat. Replacing the primary wire that goes from the distributor to the coil is slightly more involved, but, not much. While doing that, it would be a good time to replace the ponts and condensor, also, and, it's much easier to attach the wire to the points while they're both in your hand instead of the distributor. The points and condensor can be purchased at any major auto parts chain store for next to nothing. The BWD Select part # on the points is A101V for a 260 or a 289 that isn't a K code. The condensor is G125, also BWD Select. Here's how to set the points.
