its a 95 JDM b18c1 engine. so i am going to use my stock (95 cx) harness. i was just looking things over and planning it out in my head and i had a few questions before i start. first, i thought there was supposed to be an "extra" 2 wire plug for the evap on this engine or is that only for the US version? do the JDM engines have it in the regular harness? where is the evap located (i know where the canister is)? also, there is a 4 wire plug below the intake manifold and slightly to the passenger side, (green/blue, orange/black, white/red, and yellow/black) what is that plug for?

 

JDM engines do not have the evap, so no worries.

vtec wiring (solenoid/oil prssure), knock, IAB are the extras, since the car is a CX, also a 02 sensor will need to be switched over to 4 wire type from one wire (this is where the plug comes in)

 

as for identifying the sensors.

pictures would help if you are able to get some. Other wise, please describe more in detail.

 

cool. so one thing then, are you sure they have vtec oil pressure sensors too? cause i don't see one. and that plug is just hanging where i described, not connectoed to anything. it just comes out of the main engine harness and is hanging there.

all OBDI JDM DOHC VTEC motors do have a oil pressures switches, OBDII do not.

 

all obd1 dohc vtec motors have oil pressure sensor and spool solenoid harness.

 

if there is no evap system, then why is there a charcoal canister hanging off my motor?

 

so your fuel tank vapours can be contained and tehn sucked into the manifold when your engine starts...

it is an emissions control feature.

i think the EVAP is temperature controled or something and used on USDM cars?!?!

t..

 

thanks

 

so for the o2, since i'm using my stock harness, should i just run new wires to the shock tower? are the wires already there from shock tower to ecu?

 

if you vtec solenoid is like this, you dont have a pressure switch sensor.

 

ok, so i never got around to wiring my engine today (did full brake swap). i did think up a few more questions about it though.

1) will the o2 wires be in the car harness already, or will there be just one since i had a one wire o2. so my question is will i have to run wires from shock tower to ecu for o2.

2) i will have to run vtec solinoid and pressure and knock all the way to the ecu right?

3) can i run the IAB signal wire to the shock tower and hook it up with the evap wire and move that wire from A20 to A17? i don't see why not.

 

my o2 was plug and play, no wires were added
