Before you buy

The two controllers don't share every pin assignment, so check the label on your ECM before using a pinout table.

Your engine's dataplate shows the engine model, the engine serial number (ESN) and the CPL number. Compare those with the models above. If you're not sure, email us the dataplate details and we'll check for you.
