Pertronics ballast resistor removal question

You want to join the two connectors. There are male crimp-on available like the terminals on the ballast, get two of those, and a #12 insulated wire about 2 inches long. Strip the end to crimp on the terminals. Plug in the connectors, to your near zero Ohm ballast replacement. Insulate again the whole thing if you want to keep it from ever pulling apart or shorting to ground. Zip tie to harness, it becomes almost invisible.

Some cut the connectors and splice, but not easy go back for original.
