electrical help

i noticed on some of the 70s style trucks that the gasoline engines could come with a dual battery setup. does anybody have or happen to know where i could view a wiring diagram that incorporates this second battery?

Not sure what the stock set up is, but consider this: Look at a battery isolator. It allows charge, but not discharge of the 2nd battery so you can use it for other stuff, such as rv/camper etc stuff. Bought one but never got around to doing it but that was what I was going to do....

The factory installed dual battery set up was not available till 1973.

If a previous year has this set up, it was prolly installed by a place that sold campers.
