Looks like I was thinking of the right thing after reading stakon. Those will not work for what I'm trying to do. And if I am using rubber grommets I won't need a connector at all, I'll just run a continuous wire through the grommet directly to the intermittent pilot control.
The suggestion of the rtd connector from auber is more what I'm looking for but because this is a high voltage cable I'm not sure that particular one will work. It seems awfully small and I don't think it would take much for the spark to jump. Could be wrong.
