ITB Info Threat

Some intake manifolds will have an FITV (fast idle thermo valve/idle up solenoid valve). If present, it should be located either on the backside of the intake plenum, or under the throttle body. It is up to you whether you want to wire this up or not. If you choose to, there is a slight difference in wiring. Pin B2 is wired to the FITV (if present). Since you won’t be moving that pin to the B10 position, you will need an extra ECU pin and wire to extend into the engine bay. You will also need a ground for the FITV. It uses the same ground as the EACV (black/yellow). Other than this, the rest of your conversion should be exactly the same.
