^x2. you need a b series harness, try getting one out of a del slow

 

No.


What you need to do is use the STOCK harness for that chassis. If it is Dual point(2 injector) it need to be converted. If it is multi point(4 injectors) you are in good shape.

Depending on what manifold you are using, some plugs will need to be extended. Depending on what ECU you are going to run obd0 or obd1 you maybe need to run the wire for the knock sensor. And since no USDM crx/civic came with VTEC, you will need to run the 2 wires from the ecu plugs, to the motor and ground the pressure switch to the motor....or wherever you can find a GOOD ground.
PM me if you have any other questions or you need a harness made.
