Dash blanking plate

Does anyone have the blanking plate white fits this hole shown in the photo (not after the coin holder)
Also, any idea what the white plug is for that can be seen in the hole?

Shalom posted the part numbers for the blanking plates on FB. IIRC the plug is for heated mirrors.

Thanks, I am not on facebook, does anyone know what part numbers they are? can I still get them from Nissan then?

This might help.
"There are 2 versions -
one with 2 panels (68491-50C00) https://www.facebook.com/photo.php?fbid=10154869719972363&set=p.10154869719972363&type=3, and
one with 1 (68491-0N000) https://www.facebook.com/photo.php?fbid=10154869719502363&set=p.10154869719502363&type=3.
They actually come from an N15. Looks like they are both currently still available from Nissan (see amayama.com)". (Shalom Baker, GTIROZ.net)
