To replace the ECU in a Toyota Sequoia, first disconnect the negative battery terminal to ensure safety. Then, locate the ECU, which is typically found under the dashboard or in the engine compartment, and remove any covers or panels obstructing access. Disconnect the wiring harness and any mounting bolts, then remove the old ECU and install the new one by reversing the process. Finally, reconnect the battery and check for any error codes to ensure proper installation.
