    This article exploits a combination of ECU pin locations and wire colors for all M/T '92-95 Civic / '92-95 Integra / '92-95 Prelude VTEC and NON-VTEC vehicles.
    OBD1 PLUG CONFIGURATION

    Below is an example that shows the common onboard male connectors for a Honda OBD1 ECU.
    Take note of plugs: A, B, and D.

    The 4-plug OBD1 connector image below is proof these do exist and are usually found on JDM AUTO 92-95 Civic, Integra, and Preludes.
    Sorry - I do not have pin schematics for the JDM 4-plug OBD1 ecu! Although, connectors A B D should technically be the same pin locations as a 5spd 3-plug OBD1 ECU.

    ADDITIONAL INFORMATION

    These pin-out locations were cross-referenced with OBD1 Civic/Integra/Prelude Helm's service manuals.

    The information in this article applies to:

    • All US & JDM OBD1 (92-95) M/T civic ecu's
    • All US & JDM OBD1 (92-95) M/T integra ecu's
    • All US & JDM OBD1 (92-95) M/T prelude ecu's

    Did anyone try what asianboi89 posted and get working results? My car won't start, lol. I think it might have to do with the main relays being on the wrong wires. A12 and A14 are the same color wires. A13 and A15 are the same color wires, maybe one of those I have backwards? B15 and B17 are also the same color wires, those could be backwards as well. I'm not sure whether it matters though, anyone have any ideas?

    Well here's the problem with that, I've already cut the OBD0 connectors off, haha. And I don't want to give up when there's only 6 wires that could be wrong, another thing I realized is that I need an OBD1 distributor and OBD1 O2 sensor to do this conversion. So I think I'll get a hold of those and get those all wired up to see if that was the problem.
