    Take a look (search page for S13)

    Some wires run off to the right, but they all look to be earths. Also it's in Japanese, without wire colours, but it's a start.

    And

    Maybe more , but looks like you need to sign up first.

    just chuck it in, power up the black/white, the blue/red and the brown wires near the afm. hook the black/purple to your fuel pump relay, and it should run. (as well as connecting alt and starter obivously).

    brown wires are ignition, on with the key. They power the air con idle up valve mainly. They're in one of the power plugs between body harness and engine harness behind passenger side headlight.
