I am installing my Power FC and the Power FC FAQ found online notes the following, is there a wiring diagram to show which 4 wires these are? I have no idea! Thanks

<There are 4 wires that need to be disconnected from the wiring harness for the PowerFC
to work properly. These 4 wires are for extra emissions devices that were added in the
US market, but weren't in the Japanese market. These 4 wires are for the EGR valve
control, the EGR switch (the feedback in the California ECU cars to tell the ECU the
EGR valve is working), the accelerated warmup system (AWS) which gives you the 3000
RPM startup, and the Split Air Bypass solenoid, which alters the flow of airpump air to
the main cat.
There are different methods for accomplishing this. You can either simply cut the 4
wires on the stock wiring harness and tape the ends up, cut the wires and splice an
electrical connector onto the loose ends so they can be quickly re-attached, pull the pins
out of the wiring harness' connector, or break the pins off on the PowerFC itself.>

 

Figured out the wires...now the overheat exhaust light is on, what does this mean? In the guide it says the Power FC will light it up if there is a sensor problem. Ok what do I do next? How do I identify this problem sensor and fix?

 

Never mind figured it all out. WOW what a difference the PFC makes! Very smooth & solid...

 

Did you manage to get the light off?? I'm looking at doing this soon.

I take it I can cut these wires as I have no air pump, aircon, no double throttle, no CAT.

 

The PFC always lights the overheat exhaust light when you first turn on the car before you start it. No biggie.

Mine doesn't light it up. Weird.
