Thanks for the reply. The board is too large to fit into the plug shell=20
by quite a bit. Although it would be neat to build a new surface mount=20
board, that's beyond my physical capabilities at age 75 with eye sight=20
and not the greatest hand precision. :(  I could take one of those=20
boards, mount it in a small box with cable in and out, but that's=20
another piece dangling in the auto interior.

Working on getting 9 year old grandson started in electronics hardware,=20
and thought about just a voltage divider pair of resistors or zener=20
diode voltage regulator as cheap and dirty. :)

I did look E-bay, that other thread going is very similar to this one. I=20
noticed in the picture, it has the same regulator chip as my blown one.
