    hey guys-
    A buddy of mine bought a 99 LS swap for his 99 ex. We are having a bitch of a time with the wiring. Mounts are all set.

    If we use the civic harness, what needs to be changed?

    the o2 sensor doesn't plug in, the distributor has an extra plug, and so on

    if we use the LS harness, there's no way in hell that its going to reach the ECU through thr fire wall.

    If anyone has done this swap, please let me know any info you have ASAP.

    Thanks in advance

    Sorry, never done it. I don't know if it helps, but if the Gen 3 Integra is the same as the Gen 2, the wiring harness is in two parts. The part that plugs into the engine connects to the parts that plugs into the ECU at the firewall.

    I think you use the Civic harness and make it fit, extend, swap plugs, etc.

    the two extra wires are for a sensor by the oil pump I think it's a top dead center sensor or something. you don't need to hook it up. It's on my B20Z too, just ignore it.

    I put a 99 Ls in my 2k hatch and to get it wired up, I had to send the harness off to skunk2 and get an ecu jumper.
