Sierra Dissy Wiring help

Can someone please tell me what wires go where?
It is an EFI Sierra distributor (hall effect) and has a(+) a(-) and a (0).

I know one has to be 5v, one is 12v and one is reference but which is which? I am wiring up my ECU harness tomorrow so would love to know asap.

Regards,
Craig.

    I don't think they are 5V, 12V and reference..

    I think;

    + is 5V
    O is reference
    - is earth

    But I'm not 100%

    Thanks Andrew, i had another look at the wiring diagrams for the ECU pinouts and what you stated is correct. I was forgetting about the signal ground.

    Thanks again.
    Craig.

    Is it possible to wire this hall effect dizzy into a non ecu equiped car.
    and how would one do this?
    Is it as simple as puting a resistor on the +12v Ign to drop it down to 5v, 0 to the -ve side of a coil, and ground.
