Now you've come up with something that sounds like a battery equipped
LED for keyway illumination at night. If you have any imaging capability
I'd love a photo. I suppose it could be just a remote transmitter for
the UTD, in which case it will only affect your cranking circuit. If you
don't have power door locks, it ain't likley that either.

I've specialized as an expert in vehicle anti-theft systems for 6 years,
and have run across some weird crap, but anything this big sounds like
an analalog after-market gizzmo. 1.5"X 2" in '95 is enough room to put
the micro for the VCM in. It's too big. They do make after-market snap
on devices which contain batteries for LED power as indicated above.
