I had the exact same problem. And it was causing my vehicle to die and not start. I temporarily used zipties around connector and coil pack, horizontally above where the wire harness comes out of connector. Solved problems but i did go to my local oriellys and ordered a new pigtail(connector with leads).
Actually, when i did mine, i left the coil bolted to the bracket and unbolted the bracket and had plenty of room. And the pigtail i got had the same wiring colors as my factory plug. I soldered mine in using the good old western union splice and marine grade heat shrink tubing with the glue inside it. And to me #3 spark plug was the worst!
