what marking on a ribbon cable identifies pin 1 ?

I have a ribbon cable that is not labeled and does not have a notch to prevent it from being installed backwards. How can I identify which pin is #1 on the connector?

Pin 1 on a ribbon cable (the cable itself, not the terminators) is usually colored differently than the
other pins - often red.

I'm assuming you have an IDE (ribbon) cable so, typically on motherboards, they'll mark a '1' on the board to indicate pin #1. For IDE cables, newer motherboards have a open tab in the connector so that the cable you insert into the interface can only face the correct way. The interface on the cable will usually have filling tab to eliminate confusion.

Usually an arrow pointing to it, or a number 1 on the connector. It's also on the side with the red wire. And most boards are keyed with a slot on the side of the female part, and extrusion on the male connector... so it can only be inserted the proper way.
