1. In PartFinder, go to “Settings”, then click on “Mappings”. Scroll down the page to “Delete Part Mappings” and click the button to delete the existing data.

2. Go to “Fields” and click on “Add Field”. Type in “Sub-Model”, then click “Create Field” to save it.

3. In the Turn 14 Distribution app, click on Integrations. Click “Download a fitment CSV file YMMS (Year, Make, Model, Sub-Model)” to download the YMMS data. 

4. Go to “Part Mappings” in PartFinder. Click on “Bulk Import”, and upload the downloaded CSV file.
