    I'm currently doing this swap.
    93' b18a1 into a 93' Civic EX
    My harness is pluggin up fine to the LS ecu.

    My problem is the harness pluggin up to the engine.

    On the passenger side I have 3 plugs out of the firewall, Only 1 the biggest one is plugging up.

    On the drivers side only 1 of the 3 plugs comming out of the firewall are plugging up. 1 of the 3 plugs has a block plate so its not used.

    Do I just leave these un plugged? I really don't see how it would run.

    Please help. I went from a d16 to a b18c sir g and now to a b18a1. I didnt have any of these problems in my last swaps.

    I bought the cable to hydro conversion, just got it in today. [got it for $35.00 shipped] and am in the process of getting all the motor mounts brackets ect, I sold the mounts that went with my old b18c ;(

    Thanks for your time. I really do need the help, this is my only car and it hasn't been running for over 2 years.

    The engine harness right? Thanks a bunch man, I've asked this question on 10 boards, nothing!

    Ne1 kno were I can get one of these?

    the 93 is OBD1 right? I found a harness on ebay that says its obd1 and goes to a 92 93.. wont work huh?

    I have the whole car my engine came out of, would it be easier to change the harness on the car?

    I found a 94 GSR harness, will that work?

    I also found a 94 95 LS harness that goes to a automatic tranny?

    Any suggestions?

    Thanks again!

    yes the engine. the 92-93 harness will work but you have to have the 92-93 ecu. the gsr will also work too your'll have 3 plug not used(vtec, vtec oil and knock sensor) are the only three plugs not used, its even better cause if in the future if you want to swap a vtec into your car you wont have to search for another harness
    goodluck

    thanks man, what about if the harness was removed from a automatic tranny?

    I can get a pretty good deal on a 94-95 ls harness.

    I noticed however when i was removing the old 93 harness there was a plug or two going into the manual tranny.

    thanks a bunch man

    the auto may not work cause it has two extra plugs that only works on a auto tranny

    the auto harness will work.

    you can use your stock ex harness and modify it to fit as well.

    good luck.

    Thanks for the responses, I'm still looking for a harness, I should find one in a week or so.

    I think my best bet would be 92-95 civic ex harness or a 94/95 LS harness.

    The gsr's have been going for two much money.

    either way it looks like I'm gunna be spending 75$ +

    Sucks, I've spent more on lil shyet than I spent on the whole car I removed the engine from.
