I am in the middle of a H22A swap and i am trying to wire the motor right now, I am using the accord wireing harness and i have p13 ECU. There is a extra plug that was on the p13 ecu with four wires, (vtec right?) What exactly are they for? Also the lude's harness has some wires in the plugs that aernt there for the accord plugs. Do i have to swap some wires or something. Both cars were manual. I have been getting alot of different info and i am getting confused. Which wires need to be lengthened? Also did the JDM prelude use one or two o2 sensors? I bought a dc sports 4-2-1 header is it going to work. Sorry for all the ??? but any info will help. Thanks Oh and i need the car done by Fri.
