After some time trying to understand your question, as well as conjuring up what you know and failed to explicitly tell us, I think I have an answer for you.

The Vbat connects to the automobile's battery (e. g. 12 VDC). The 7805 voltage regulator provides +5 VDC from the auto's +12 VDC for all IC's that need it. All +5's and all Vbat's are connected together on the circuit board.
