Okay I put this motor in my car a while ago and am just now getting the ecu and converting to 0bd1. I was told that I have to have the 4 wire o2 sensor for this but on the manifold that came with the motor there is a 1 wire sensor. Did the people I bought the motor from just switch it or can I run 1 wire?

 

If you are OBD-1 then you need to match your ECU.
Get the right O@ for your ECU - 4 wire.

The ECU will be looking for the 4 wire for it's heater circuit.
Without it you will get a nice fat ECU code.

 

alright. I'm gonna be running the p28 so.. That needs the 4 wire right?

 

run a serch..

 

don't tell me to search. I did and didn't feel like doing it 10 times to find somthing.

 

oh and were is a good place to get one. other than a junk yard.

 

Never mind. I found one on ebay.

 

i have a couple of stock d15b7 o2 sensor if u want.

 

i just did my swap.

make sure you also have 92-95 civic injector clips. the resistor box will need to be removed. get a 4 wire from ebay

 

but I don't have to switch to obd1 injectors. correct? thats what I heard anyway. I was planning on it though so While the subject is here I read on a write up on here that you just the the Injector box out/off and just soulder all the wires together and then put electrical tape on them is this correct? don't wanna funk up my car because I also heard that if you cut those wires that your car will catch fire.(maybe if they arent souldered correctly or if your supposed to be running with the IB?

No, you don't have to use OBD-1, OBD-2 injectors. You can use the preOBD ones and keep the injector resistor box.

Since you are going to use the OBD-1 injectors, all you do is cut the green injector resistor box plug off and solder all 5 wires together and tape them up/shink tube them.

 

cool. I'm trading my obd0 injectors for the obd1 injectors to some guy here were I live so I'm not really losing anything. I'm also getting the clips.

 

Also on the obd1 cars the ecu light is in the dash or somthing correct? I know there isn't one in the ecu so how do I check the codes? or were do I wire a a little light up to on the ecu if you can?

 

N/M I figured it out.
