Aftermarket Headunit - No clue what I need.

So, I have absolutely 0 idea what I'm doing when it comes to electronic stuff.

Recently picked up a headunit that would allow me to use bluetooth/aux/etc, but largely it has (or at least should have) a working cd player, unlike my oem unit.
However, it's just the headunit, and it doesn't have the same plugs.

Aftermarket (Dual Electronics XHD7714) on top, 2000 NB OEM on bottom.

Does anyone have any idea what I need, or where to go to find out? I am at a total loss here.

Any help would be appreciated.

The seller of the aftermarket unit should have included the harness for that unit, which could be connected to an adapter harness. Without that, the swap will be very difficult.

By the way, if the original unit is a Bose unit, the swap will be a bit more difficult.

Hope this helps.
