Question about the electrical ground

I need to know if my 1979 F150 Ranger XLT has a positive or a negative ground so that I can put a cb radio in it. Please let me know.

Welcome to the site.

Positive ground was an British Auitomobile thing.

IIRC, Positive ground in America was gone before 6 volt systems.

Most batteries are marked + or -

the Negative cable will go to a ground source like the egnine block.

where you can power your radio from if you wish.

I know that Ford did have a 6 volt, positive ground system in use on the '49 F-1 with a flat head V-8. I helped my best friend completely restore, then street his '49 F-1 and that is exactly how it was wired.
