    Ok since alot of people want to keep this info hush hush or what not. I have done countless hours of research and looked up on many forum and manuals etc. There are some people who are helpful and some who are not. I am putting this together to help the ease of J swaps in the future.


    hopefully i covered the jist of what needed to wire up the J32a2. if i did not please feel free to correct me. Also hopefully this gets stickied! :D

    Please if you use this info, Please give credit to me "EJ32A, FerioEK247" aka Anthony L., for doing all this research and etc. Also credit to TwistedImage aka Chad for confirming shock tower wiring, C131 wiring from his Auto to manual swap.

    Anyways this "how to" will cover

    1. C131 Plug - green plug: located by passenger kick. it helps run some function to the cluster

    2. Civic C101, and Acura C101 & C102 Shock tower plugs: wiring conversion

    3. Auto J series engines "A" plug for ECU wiring

    4. Manual J series engine "E" Plug for ECU wiring

    5. Secondary O2 sensor wiring "buy a female plug end and run extra wires to reach 2nd o2 sensor."

    6. CL type S cluster: wiring "optional WIP"

    Somethings are optional, but this is pretty much all you have to hook up to get it fired up and running...
    ------------------------------------------------------------------------------------------

    tid bit: 96-98 engine harness is one piece that comes with green plug. But 99-00 the green plug is separate. which need to be wired up. if your like me, and have one car. goto the junk yard and pick up a male end plug off a civic from 96-00 from the interior.

    "A" auto ECU and "E" manual ECU plugs are 90% same as for wiring up to the C131 plug and ECU. So all you have to do is wire the C131 to the


    1. C131 green plug - located at the passenger side kick panel. It wires up to the main interior harness which as well to the cluster. "Thanks to TwistedImage for confirming my wiring"

    There are only 8 wires the need to be wired up. From the "A" auto ecu plug, and the "E" plug Manual.

    below is "A", "E", and C131 Pinouts

    ok use the pictures above for reference and wiring up your "E" or "A" plug to the C131 green interior plug.

    "HOW TO" wires need to C131 wiring.
    C131 green plug Civic, goes to "E" Plug/ "A" Plug


    Pins-------Color-------Description
    6-----------Green---------Fan Control "tap in-between "A" or "E" plug and C131 to Tempsensor green wire"
    8-----------Green/Orange---------MIL "Malfunction Indicator lamp"
    9-----------Brown---------Service Check Signal "For DLC"
    16---------Green/Red---------ELD "Electrical Load Detector"
    17---------Green/White---------BSWS Brake switch signal
    18---------Blue/White---------VSSout Vehical Speed sensor output
    20---------Green/Yellow---------Fuel Pump Relay
    21---------Blue/White---------K-line "for DLC"

    that should all be needed to wired the C131 green plug.

    -it is quite simple, to hook up. follow the steps below, then voila!


    "HOW TO" Shock tower wiring


    - Merge all Black/Yellow wires together
    -2 off civic plug
    -2 off CL engine harness
    tip
    - Cut both C101 and C102 plugs off CL Engine Harness, and extend 7-8 inches to reach the Civic/integra female end shock plug.


    90% of wiring match up.

    Civic C101 plug Cl type-S C101 and C102 plugs

    Pin-----Color----------------Descripton----------------connects to

    10-----Black/Yellow--------Ignition 1----------------Merge to all black/yellow wiring to single wire
    9-----Black/white-----------Starter signal----------------C101 10 pin plug, pin 9 "black/white"
    8-----Blue------------------- RPM/Tach----------------Run extra wire all the way to the ECU "E" or "A" plug to BLUE "NEP"
    7-----Yellow/Green--------Temp Gauge----------------"not used"
    6-----White/Blue-----------Charging system light----------------C102 14 pin plug, Pin 14 "white/blue"
    5-----Yellow Black----------PGM-FI?----------------C101 10 pin plug, pin 7 "Yellow/Black"
    4-----Brown/Black----------ECU Ground/logic ground----------------C102 14 pin plug, Pin 5 "Brown/Yellow"
    3-----Yellow/Red-----------Oil Pressure light----------------C102 14 pin plug, pin 1 "Yellow/Red"
    2-----Black-------------------Chasis Ground----------------C101 10 pin plug, pin 5 "Black
    1-----Black/Yellow---------Ignition 1----------------Merge to all black/yellow wiring to single wire

    there will be a lot of left over wires from CL harness which is not used. so mask or wrap off.

    -CL C101, Fan Control "green" wire runs extra wire to Thermostat plug "tap into green wire".

    3. Auto J series engines "A" plug for ECU wiring

    13--------Blue-----Immobilizer Enable signal -----runs to ignition by key "same color wires"
    25--------RED-----Immobilizer Code -----runs to ignition by key "same color wires"
    20------Green-----Fan control -----C131 plug, pin 6, green

    tip

    -when wiring immobilizer, the last remaining wire is

    black/white - Connects to "A" plug sG1 "sensor ground"
    brown/yellow - Connects to "A" plug LG1 "logic ground".

    Optional for emissions

    28 - Light green - FTP Fuel tank pressure sensor

    so instead of spending $550+ do it for free

    Hope this helps will post CL-s Cluster wiring to civic a bit later after i work more tweaks out. Enjoy


    also here is a video of it running.

    I followed EJ32A, FerioEK247, and TwistedImages how-to thread to the T on J32a.com. While their how-to is awesome and gets your car running and mobile. For the ppl using the Auto engine/ecu swaps this still doesn't get the vehicle out of limp mode. It lacks the DLC wire up and secondary o2 pin out/wire up. After hooking up the Secondary o2 and Speedo you're still in limp mode also the Reverse lockout, then theres the myth of the B14-D14 pin tie together (which still doesn't get your vehicle out of limp mode).... so here's my question on your swap how did you get your car out of limp mode or did you do the usual switch to AEM's stand alone ecm? Not trying to discredit or knock them down from their pedestal in any means because the secondary o2 wiring DLC port and other how-to's are on j32a.com's forum but this seems to be the biggest question from everyone is "how did you get it out of limp mode."
