The ECU is under the passenger footwell. Peel back the carpet, you'll see the metal cover that's over it. Remove that and the ECU is underneath. Disconnect the battery before unplugging the connector and messing with the wiring.
Also note that the TT will only be able to tap into the rear 02, same as the cheap A/F gauges, so it won't be getting accurate readings.
