Hey I have a quick question... when putting the h22 in the 5th gen accords are there wires you have to lengthen??? It says so on h22.org or whatever it is... I was just wondering before i started cutting the wires! I am aware of adding some i just wasnt sure if it was necessary to lengthen some of them@!
*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 harness with a large enough splice.
