    Can someone please post a pic with the location of the cat ECU on a 2.7 355. I searched the forum but only found pics for the 5.2.

    I am looking to disconnect it as I'm running test pipes.

    Don't have a photo on me, but it's directly under the ECU on each side.

    Go under the ECU connector, and reach your arm further into the side of the vehicle. You'll feel a box with 2 connectors into it. Those are the Cat ECU's.

    Should be an even easier solution by messing around with the thermocouple wiring. Forgot exactly what needed to be done. Will look for a thread.

    Thanks. And which of the two connectors do you disconnect? The one with the wiring I'm guessing the other has what looks like a ground cable to it...

    The ground cable is the shielded thermal couple. After you remove the TCU, the thermal couple is no longer needed.
