    I hope this helps, if you need more info, just email me.

    * Wires to add:
    VTEC Solenoid: Grn/Yel on Prelude harness > Pin A4 on ECU // SENSOR LOCATION: Near distributor
    VTEC Pressure Switch: Lt Blu on Prelude harness > Pin D6 on ECU // SENSOR LOCATION: Near distributor
    Blk/Red > Ground
    IAB: Pink on Prelude harness > Pin A17 on ECU // SENSOR LOCATION: Drivers side of intake manifold
    Blk/Yel > 12V
    Knock Sensor: Red/Blu on Prelude harness > Pin D3 on ECU // SENSOR LOCATION: Middle back of block
    * Sensors to lengthen:
    (NOTE: Consult the helms for the location of sensors, and color code of the wires on your harness.)Colors below are for the Accord LX harness.
    IAT (GRN/BLU-RED/YEL): Too short, needs to reach drivers side of intake manifold.
    MAP (YEL/WHT-GRN/WHT-WHT/YEL): Too short, needs to reach wherever on the firewall you mount the MAP sensor.
    EGR Lift solenoid (GRN/BLU-WHT/BLK-YEL/BLU): Too short, needs to reach passengers side of intake manifold.
    H02s (GRN/BLU-WHT/RED-ORN/BLK-YEL/BLK): Too short, needs to be run to O2 sensor, near oil filter.
    IAC valve (BLK/BLU-YEL/BLK): Too short, needs to reach top of intake runners, in the middle.
    ECT switch A: This will need to be extended to the thermostat housing on the passengers side of the back of the head. The ECT sensor and ECT sending unit fit fine (under the distributor.)
    *NOTE: There is no ECT switch B on the JDM H22, just spare back the connector.
    Alternator: The power wire on the alternator needs to be lengthened about 2". We just cut the one off the Prelude harness, and attached it to the Accord harot;. ness with a large enough splice.
    *NOTE: SWITCH WIRES A6 (EGR solenoid) and A11 (H02S heater) at the ECU
    When you think you have everything wired up correctly, plug in the brick and turn the key. Have a multimeter ready to troublshoot if you throw codes. Remember, some of the sensors may be bad so don't run yourself into a wall thinking you wired wrong. (Although you may have.)

    I found that on the net. By the way, the pin switching only applies to newer accords than ours.
