Can anyone help me identify the wires in this picture that goes thru the firewall. Need diagram or wire color and what they do. This complete harness was inadvertently removed and they cut these wires. They stripped wires from the harness not needed for a swap.

C21 - 18DB/YL - AC select
A1 - 12RD - fused battery power
G4 - 20DB - fuel level

thank you Machoheadgames. now I can follow diagrams and straighten all this out. Thank you sir.
No problem. Good thing is none of those are critical to operation except the 12ga battery wire which goes to the ignition switch.
