Installation and Setup
On the 2008 Isuzu I-370, the ECM is conveniently located on the right-hand (passenger side) of the firewall in the engine bay. Installation is straightforward for a DIY mechanic with basic tools. After disconnecting the battery, simply unplug the electrical connectors, unbolt the old module, and install the new one.
