    hi i have a 91 civic that i just put a 90 integ b18a1 into and i was just wondering if anyone could tell me wich wires i have to change or splice for the wireing harness i have both the integ wire harness and the civic is an si harness (the previous owner spliced it cus car is a cx and he did a zc swap) i have a friend who is going to do the wireing for me but hes taking to long to start it and well i really just wanna get to driving this car so if anyone can tell me wat i have to do to the wiring harness to make this swap work would be great

    If your car is an Si or already converted to Si spec it will be pretty much a plug and play, you may have to lengthen a few wires here and threre.

    well the si motor is a d16a6..the zc is not the si motor...its kinda like it(if its sohc)
    but we need to figure out the chassis before we can do wiring..
    if its si or hf then the motor harness will plug right into the motor(if its obd0)
    if its anything else you have to convert to mpfi

    well its obdo and ya its a sohc zc so its the japan version of the si from wat i have heard and i have friends that say that im gunna need to change some of the connectors like splice in some of the connectors from the integ harness to the civic harness i havent really tried to plug in the civic harness because im afraid im going to f something up so thats why im comeing on here and trying to get as much info as possible since this is my first motor swap on a honda and well this is going to be my daily driver so i dont want to be shorting anything out and making more work for myself cus i already tried to fix my zc tranny wich i broke the first/second gear fork (reason why i am swapping ) and im just really gettin tired of workin on this car so if ur sure that all of the connectors will fit i will try it tonite and if i run into any problems i will post them

    if it has a SOHC ZC in it now, the 90 B18A1 should just plug right into everything - it would be best to use the 90-91 Integra PR4 ECU

    from what i understand, it is more like a cross between the US DX and STD - has D15B2 and 5 speed but no tach, etc. like a STD
