I inherited a an older big bear ATV from an estate, but cannot locate a VIN number. Could anyone help identify what year this ATV is based on these pics? I am trying to troubleshoot an electrical issue and need to find the corresponding wiring diagram for this ATV.

Try this. Where is the VIN number on a Yamaha 350 Big Bear? Image result for How to identify year of Big Bear 350 Location: Always on the left side lower frame rail between the A-Arm Mounts and Engine (Sometimes hidden by Mudguard/Plastics). All Terrain Tech Tip: Use a Rag to clean, flash light and possibly wire brush. Important: The number will be 17 Digits.Oct 1, 2021

Welcome from Colorado.
Look for the vin # stamped into the lower frame rail, left side just behind the rear a-arm mounting point.
Is there a Yamaha sticker under the seat?
