You need to track down that pink wire that originally went to your coil. Trace it back to the bulkhead and replace it from there. Then you will be good to go and not cobbled with extra wires. The only other thing it could be is a bad connection at the bulkhead and that's not likely. When you start tracing the pink wire I think you will find your problem. There's also a slight chance it could be your switch. A little testing with a meter or a light bulb will quickly get you where you want to be.
