Step 5: Tap the wires

Using the above diagram, tap the red, black, green wires first. Since those don’t require any cutting.The Map sensor wire requires cutting. There wasn’t much room to work with so I just cut the MAP sensor wire half way.Attach the yellow wire from the AFC into the wire to the ECU. Connect the white wire to the other end. NOTE: DO NOT MIX UP THE WIRES FOR THE MAP SENSOR! I did the 1st time, got a check engine light, and the car died.

Here is a picture of the installation, I will tidy it up later, but it is winter now, and its too cold outside!

Step 6: Clean up
Check that all your connections are tight, and put everything back to where it was. Also, make sure that all your settings are 0% 0% 0% 0% 0%. After everything is done, reconnect the negative battery (and don’t forget to set your clock!!)

Step 7: Go for a drive
Start the car. It should idle a little high (1000rpm), but once the engine warms up, it’ll be back to normal (750-800 rpm for me). There should be NO check engine light!If there is, shut the car off immediately and check your connections!!!! Do not try to adjust the settings of the AFC, WITHOUT a DYNO! I’m not responsible for you leaning the engine out and blowing up your block! Although running extremely lean will make more power, it will also make your wallet unhappy from the engine swap.

Step 8: Setting up a AIR/FUEL gauge (Optional)
For those of you who also want to install an a/f gauge, you can tap into the ECU wire 5B or 6B. It’s the pink wire from the O2 sensor.

Step 9: You’re done!
It took me around 4 hours to install the AFC. But I had help from my brother. So it may take you longer! If you have no previous electrical experience, then I would not recommend you do this mod, but you are always welcome to try! Here is the picture of the AFC at night. The knobs light up green, and the rpm you are at light up as red. When you rev the engine, it gradually fades to the next knob. Very cool to watch at night!!!ENJOY!
