I did a blacktop 20v into an AE82 so it may not be the same, anyway here is how the body loom looked on mine
Black - tacho
big fat white - +12V
big fat black - starter motor
Black/yellow - +12V for Alternator
Yellow/white - Charge warning light
Yellow/black - oil press.
yellow/green - coolent temp
green/red - fuel pump relay
also there is +12V for injectors and +12V for coil, but i can't remember what colour they were.
The 20v is hard to wire if you have never done it before, better off getting it done proffesionally
