Get the ECU pinout out of the Factory Service Manual. Near the end of the manual, there should be a pinout for the ECU. Use this, with the instructions from Apex'i for the installation.

Pinout is on pg. EL-106. You'll need to use the wiring schematic on the remaining pages and follow from the sensor to the appropriate number on the ECU harness. Remember, the pinout is showing from the harness side, not the side that plugs into the ECU.
edit: Not to be a jerk, but this is a pretty basic schematic, if it overwhelms you, this is better left to someone with experience. You don't want to fry the harness, ECU, or car. :twocents:

Keep it confined to 1 thread por favor.
Have you tried emailing/calling apexi to see if they can provide the manual?
For future ref...these are things to find before undertaking doing your own mild tune work.

and also boostinx yes i cant get in contact with them for one and another thing im not sure how to properly input setting on the safc unit i am not knowledgeable of electrical and electronics my expertise is on working on the mechanical aspects of vehicles i have seen forums with
in should be 02 out should be 05
this setting is 1% this one is 3% etc....
i hope to get it easy as that then my car is done. i do not want to fuck up my engine with a incorrect tune because i have nobody to assist me and im not experienced with tuning

Get the manual and set a stock tune based off the instructions in it. I guarantee the manual has instructions for the base tune, I've installed AFCs in the past. Then, once your car is running, take it to an experienced shop and have them tune it. Bad things can happen very easily via AFC, if it's tuned by somone inexperienced.
