Spitfire Cigarette Lighter

[Douglas Braun & Nadia Papakonstantinou <dougbert@rcn.com>]

Does anyone have an original cigarette lighter on their Spit?
I don't, and I would like to have a place to plug in my
car phone charger.  I need to know where they
mounted the thing, and which circuit it was wired into.
Also, was it even a factory option, or just a dealer-installed accessory?
This is for my '72.

Thanks,
Doug Braun
