Car restorer note:  The equipment used in any given vehicle as it came off the production line was documented in the installation guidebook for that particular car, printed by CHP's Motor Transport Division.  These were for the most part printed annually, e.g. 1992 Mustang, 1995 Caprice, etc.  These booklets contain wiring diagrams, part numbers and drawings showing how everything was originally put together.  These are not publicly available anywhere that I know of, but some of them have been scanned by enthusiasts and are floating around the web as pdf's.  A lot of the information here comes from those books.  When restoring a car and trying to be as authentic as possible, these booklets are invaluable.  Try to find one of these if you can as it is going to be almost impossible to get things correct without it..  If you have any of these booklets and can scan them, I can save them here to help people who may need them.  I have the 1995 Caprice and 1992 Mustang and the wiring diagrams for 1968 Dodge cars.  Also some for newer than 2009 Crown Victorias and the Watch Guard video system.
