Dale - I mis-spoke.  I just pulled the "book" on mine and it is from
Norm's Rotor Service, called a BD189 Brake Delay Unit.  It appears (in
the sketch) to be just a small relay with large cap to delay release.  I
haven't opened the box since I installed it last year, so can't confirm.

There's a small picture of it here:
