Need help to cable motherboard

I have to replace my motherboard and one of the cable is still unplugged.
Could you please help me to know where I have to plug this cable.
Hereafter motherboard and cable.
Thank in advance.

In The SV06+ it’s unplugged because the filament sensor uses that plug.
In The SV06, it’s unplugged for use if you install a filament sensor.
That plug leads to the unused plug on the right side of the hotend.

It is what I think but I was not sure.
Thx a lot

By the way, did you notice that almost all the connectors were stuck in their sockets ?
Very fun to unplug.
