I just installed a 01 gsr(b18c1) in to my 96 civic hatch cx.Stock harness still in with a p72 ecu 96 integra gsr. I still have the engine harness from 01 gsr which is a obd2b i believe. So my question is what sensor's do I need to pin into the ecu?

 

you need the knock sensor, the vtec solenoid and vtec pressure switch (jdm doesnt need a vtec pressure switch if you have ecu) and the IAB (dual butterfly) from your manifold.. then u gotta make the conversions for the IAT plugs, you gotta cut it and take the round plugs and retro fit it. The IACV plug has to be modified too.. since the stock harness has 3 wires, the gsr has 2 so you need to cut the orange one and retro fit the 2 wires..

 

check this page.. it has a great guide to swapping in a b series vtec engine to ek dx chassis.. http://technet.ff-squad.com/

 

okay what about on the 98 Lx chasie..with its stock harness...
