I have heard that it *may* be necessary to add additional length to some wires on the JDM H22 harness so that they can connect with the S model in-car harness. Some people said they had to do this, while other write-ups never mention it. I've already got all additional wires for VTEC/knock/IAB etc figured out. Does anyone who did this swap recall WHAT wires needed to be lengthened? . I figure it would be a lot easier to lengthen the wires BEFORE dropping the engine in. I found a write-up about doing the swap into an f22 equipped 1995 accord , do you think similar mods would be required for the Prelude harness? :

"* 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.)"

Thanks in advance for any help
