Hi!
I got -71 Eldo Coupe and found unknown silver-colour box installed in the bulkhead. It is about 5-6 inches long. There is one wire, but the other end is not connected anywhere. To me it looks like towing sensor for aftermarket alarm system.
Any other ideas?
Best regards,
Matti

Looks like one of the very early motion sensors for Anti-theft.

It senses irregular movement of the car and sets of the alarm.

Like a bump in a car park, or someone trying to open the door before the unit is disarmed, or even popping the hood.

I have not seen one of those in several years.  That's how long it been since I have seen that part of my closet.  Like mentioned above it’s a motion sensor, with a weight and rigging to keep it centered in a ring.  If the car is shaken the weight moves and grounds the wire coming out.  Just hook it up to the horn with a cut out switch and your all set.      IIRC the screw next to the wire terminal is a sensitivity adjustment.

Yup.  I used to install these for people.  It was called a Devil Dog.
You could set the sensitivity so that ANY movement of the car would cause the horn to blast.

You can safely remove that and follow the wire back to the connection into the horn circuit and eliminate it.

Thanks! I will remove it. The wire is not connected anywhere so no harm to remove it.

Neat.   Who knew Mitchell was not only home to the Corn Palace (aka the worlds only civic arena covered in corn) but also the Devil Dog.     I assume that was something you could order from JC Whitney among others?     I think I may have even seen that exact one in one of my past cars.   I have also run into similar devices with no name that after I tore them apart figured that must have been what they were.

And next one from the same Eldo: is there supposed to be such foam, about one inch thick, under the rear seat? I don’t think so.

In a word, no.

Someone has put it there possibly to try and add insulation under the seat base, or possibly to stop a squeaking from under the seat.

The trouble using foam is that it will absorb moisture, which in turn causes dampness, and encourages rust.

Thanks. Very interesting to dig into a new car and try to understand what PO has tried to do with several odd things here and there!
