I have 2 good batteries, good connection on terminals. Interior light works, headlights work. No power to anything else no dash no fuel nothing. Oh the door locks work and the door buzzer. Any ideas?

 

I saw your post and I was curious if you have seen any codes showing up? Below is TSB that may be of some help.
