Questions about this item

Do I need the original palmrest and motherboard from a Latitude 7420 for this Y1JC3 ribbon cable to fit?

Yes, this genuine Dell OEM cable is made to connect the palmrest junction board to the motherboard inside a Latitude 7420, so both original parts must be present.

Will this cable work if I keep the existing GDC41 or NBX0002QK00 board in the laptop?

The part numbers GDC41 and NBX0002QK00 are listed as alternates for Y1JC3, so the cable is designed to mate with those same junction boards.

How can I confirm the cable is seated correctly after installation?

When the connector clicks fully into the motherboard header and the palmrest USH functions — such as fingerprint or smart-card reading — operate normally, the cable is working as intended.
