need help with coil wiring

Correct. Get the +12 V "ignition power" from the "coil+" wire where the factory coil was. Remove the ballast and jumper the 2 terminals together, as 67Dart273 says. I used a special male-male spade connector, but you can make a short jumper wire. If you car had factory electronic ignition with the dual ballast, it gets a little tricker, but not too tough.
