Before you buy

To be upfront about quality: this file is a scanned document and its text layer isn't perfect, so searching the PDF may miss things. Read pin numbers from the drawing itself rather than from copied text.

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.
