How are pins numbered on an obd?

On an OBD (On-Board Diagnostics) connector, pins are typically numbered in a specific sequence, usually starting from the top left corner and moving left to right, then down to the next row. For example, in a 16-pin OBD-II connector, pin 1 is at the top left, and pin 16 is at the bottom right. The numbering may vary slightly between different types of connectors, but standardized layouts help ensure consistency across vehicles. It's essential to refer to the specific pinout diagram for each connector type to identify functions accurately.
