    whats up all, im in desperate need of a wiring diagram/schematic for a 1991 honda civic dx. i need to know what wires are what for the ecu but i dont need a pinout or anything, if that makes sense. im in the process of doing my own obd0-obd1 wiring conversion and i wanna make sure im not using the wrong wires and start a big fire lol.

    Well I can help you out! I was looking for the same thing and i understand what your getting at but the diagrams are 95% accurate. The HELMS manual is 99% accurate.

    The problem with what you want is that the DX model uses the same colored wires for different components. The manuals say to read the pinout #'s from left to right, top then bottom in order from the wire side of the female end.

    The harness should be read top->bottom from left to right from the wire side of the female harness.

    I hope that this helps you. IF not, then i have taken off the wire looms from the main harness and i plan on seperating the wires into "plug" categories. Shouldn't be too hard.

    ECU
    A=20
    B=18
    C=16
    total =54 wires to track down!!
