If you don't have a drawer full of those that you got for free, you aren't
doing it right.

It took me a long time to wrap my head around the way that system actually
works.  I finally got it, but I've still never actually seen the ballast
wire.  Back in the day, I sold plenty of ceramic resistors for Chryslers,
but I assume the wire is buried in the harness somewhere?
