i know this has been beat to death but i searched it already and could not find what i was looking for could some please point me in the right direction.

what i am looking for is info on wiring vtec which i have found but i also need to wire 4 wire o2 onto my cx also i am using an ex harness i just need to know what pins from what connector goes to what ecu pin and such.

 

Plug A (largest plug)
A6 -> heated oxengen sensor orange/black

Plug D (Second Largest Plug)
D14 -> O2 sensor white (should already be there)
D22 -> sensor ground green/white

other black wire goes to fuel injector joint connector? turns into yellow black

 

Update, it seems that "fuel injectors joint connector" is the plug on the drivers side of the car that goesn't plug into anything, its near the drivers side of the engine compartment and has a cap on the end, all the wires going into it are yellow black this should already be wired if you are using an EX engine harness

 

^ if you use an ex harness it will just plug in. the 92's came pre wired for vtec. plug in the harness and the ecu and done.

 

Yeah, thats what i thought too, then i read his post a second time, he already found the vtec wiring, he needed the 02 sensor wiring, which as far as i know isn't in the us cx cabin harness

 

yeah i need the o2 pin out and the connector info but i put the wrong year model on here it is a 95. i really don't even need to run the o2 cause i have hondata.
