What are three ways you can best identify which adaptor you should use for the vehicle you’re servicing?

Check the Vehicle's Manual: The vehicle's manual often contains detailed information about the type of adaptor needed for servicing. This should be your first step in identifying the right adaptor.

Look at the Vehicle's Ports: Different vehicles have different types of ports for adaptors. By examining these ports, you can often determine the type of adaptor you need.

Consult the Manufacturer or a Professional: If you're still unsure about the type of adaptor you need after checking the manual and the vehicle's ports, you can consult the vehicle's manufacturer or a professional mechanic. They should be able to provide you with the information you need.
