Where can I find data sheets or specifications for automotive parts such
as relays and switches? (Amperage ratings of contacts, pin and internal
component diagrams, duty rating of relays - continuous duty, etc.)

Relays are easy - the common ones tend to be 30 amp.

Here's the pinouts:-

As regards switches there are so many in use it would be difficult to give
ratings for each and every one - especially since so many no longer switch
things directly, but just operate an electronic switch.

But if you know what the original app was and it was switching direct
would be easy to make an educated guess.

The same firm does a range of modular rockers and they're 15 amp.
