P.S. Extra bonus question, any way to just figure what the old ones
had for a filter?

I'm not sure why a filter would be required- looks like you could
reduce the sensitivity using shielded wire and maybe a single turn
around the ignition wire. No?

I'm going to play more with this idea. the vendor had me cut the lead
down to one inch and use just a hook, no joy. I think I'll try to
increase the distance by wrapping a gob of elctrical tape around the
plug wire.

I assume you're thinking AL foil. Which wire would you wrap, plug wire
or unit pickup lead, and should it be grounded?
