Mystery part?

Nice that the module's been replaced. We had a 1983 E350 and the OEM module never actually quit. But the epoxy-or-whatever "potting" that protected its internals got old and tired. Sometimes we'd stop at a rest area on a hot day and the thing'd drip hot goo on the pavement. I carried a spare and finally cleaned the goo area up and installed it. Just couldn't stand the look.

If yours has the cylindrical ignition coil (metal "can" with plastic terminal end), a spare one of those is a good idea. They get hot and tired. May not re-start on a hot day. We actually had one shut us off on the road. Rolled into a service station and found it'd start again once it cooled. Replaced coil and had no further issue.

That's a BLUE grommet ign control module. The color of the plastic where the
wires come out id's what cars/trucks it fits.

Thank you everyone.
GMandJM got it. I went to Napa's website and searched for Ignition Control Module and found it. That's what it is.
Thanks for humouring my curiosity.

Since it is a NAPA part, I would go to the local NAPA dealer and ask them. If they are like mine they will know right away what it is. JMO

my guess a headlight relay for the old round headlight high beam

Power for HID lights?

Is there a NAPA P/N on it?

Seems the picture isn't working. This link should take you to it.
