Installing a FCD on a Toyota Celica GT4
This page contains details of tools required aswell as how to wire up the FCD. The instructions are based on a GT4 install however the principles are the same for any turbocharged car.

Fitting the FCD is relatively simple however you will need to gain access and 'tap' into some of the ECU wires. Failure to follow the instructions correctly could cause damage to your ECU. If you are not confident in carrying out these instructions - seek help or advice before proceeding.

Locate the ECU and centre block connector
the ECU behind the centre console by folding away the carpet revealing
the 3 main block connectors. On a RHD model the ECU block connectors
are on the passenger side of the car.

diagram). For 1992 onwrads cars, this is normally pin number 5 on the
centre block connector i.e. fourth along from the left on the top row.
For cars earlier than 1992 this is normally pin 13 on the centre block
connector i.e. fourth along from the left on the bottom row.
