Ok I have had a few requests to write down some instructions on how I installed my o2 simulator. First of all I recieved mine from the Bushcur Racing to be used with my off road test pipe for off road use only . Some other sims might be different but it does look the same as the one that the lancer shop sells so just everyone knows. Please let me know of any feedback and I will add it in to help everyone out.

STEP ONE
Locate the cars o2 sensor plug for the rear o2 sensor. This is under the passangers seat on the upper left hand side of the floor. You will notce a box type slit in the carpet so you can pull it back and reach down in and get ahold of the plugs to pull them out for access. I took my seat out for easier access, to do this you remove the rear piece of the armrest console by taking out the two screws under the armrest in the storage compartment then pulling up on the assembly. The rest of it is only snapped in, when trying to remove it will only remove from the armrest up to the end of the cup holders taking the intercooler switch, the shift column and console will not be affected or moved. Once you have the armrest console out you can see all 4 bolts for the seat. Slide the seat back then take out the bolt and then remove from the car carefully not to bump or scratch anything.


STEP TWO
Once you have easy access to the cars o2 sensor wires on the o2 sensor plug (Black) side you will want to trim the shielding then you will be able to see all the wires (List out below in order), next you will be cutting the blue wire becuase it contains the voltage that is going to be altered by connecting it to a input and output wire from the o2 simulator. When cutting this wire you want to cut far enough back to give yourself room to strip both ends and still have a inch or two left to access so try to cut the middle of what you can see from the floor.


STEP THREE
List of wires from the o2 Sim
---------------------------------------
1.Solid Black
2.Solid White
3.White with a black line
4.Solid Red


List of wires from the o2 Plug from the car on the o2 sensor side. Do not cut the wires on the car wiring harness side only on the 02 sensor side becuase it can be replaced very easily. The correct plug is BLACK.
-----------------------------
1.Solid Black
2.Solid Black
3.Solid White
4.Solid Blue


Connection order from the o2 Simulator to the o2 Sensor Car Plug (Matching numbers)

1.Solid Black = Car ground (I grounding on the seat bolt on the upper left and ran wire under the carpet)

2.Solid White = #4 Solid Blue going "IN" from the cars o2 Sensor. This connection is a "SOLID" connection.

3.White with a black line = #4 Solid Blue going "OUT" to the cars o2 Sensors Plug (BLACK). This connection is a "SOLID" connection.

4.Solid Red = #2 Solid Black on the cars 02 Sensor. This connection is a "SPLICE" connection.

NOTE: Wires #1 (BLACK) , #3 (WHITE) don't have any connections.

STEP FOUR
Once all your connections are made you should tape everything off reconnect your plug and then tuck everything up under the floor that you can, I left the o2 Sim hanging out becuase when your key to the ACC position you should see the red light flashing. This will indicate that the o2 sim is working so you can check it when needed incase of problems later on.


STEP FIVE
If you have identifyed everything is work you will need to reinstall your seat then your armrest console.


STEP SIX
Preform an ECU Reset to get rid of the light in most cases. Not all people have had to do this so this is your call, I did the rest.


I hope this helps, my light has been out for quite some time but it did come back when I was running very rich after I installed my walbro fuel pump. So a correct fuel trim could be a factor in this as well. Also there has been methods of drilling out the bung on the cat back pipe, mine has been drilled out a little so that can play a factor as well. These are just factors and tips that I wanted to share but I hope this helps everyone.
