    Are you needing the entire wiring diagram, or is there 1 or 2 wires you need help with. There will be more wires on the 89 and more vacuum stuff on the 85.

    The wiring is completely different between a 1989 TBI equiped motor and a electronic Q-jetted 1985 motor.
    I am not saying that you could not figure out what is what and adapt plugs and terminals but that seem's like it would be a nightmare with all the vacum related hardware on the 1985 motor.
    Post up info on the exact motor you are putting in and maybe someone with the ability to post pic's of a Helms manual will do so .
