Well there ya go. My '87 Vgon is the most 'modern' model year I have... 'tho
my '85 Caddy has more bells and whistles. It would be interesting to combine
the two effects- activating the 'accessories' circuit with the key (or a
button/switch, or either) and having it deactivate with an opening door, or
just the driver's door, if preferred.

Cya,
Robert
