Terminating oled display

[AmigaTim]

Morning,

I wonder if anyone can offer some advice.
I have had to remove the 4 black plastic square terminated ends to feed through the cables of the oled display of my gotek drive so i can mount it on the top as im getting a stiff neck peering to the side of the amiga to see it.

What are the black plastic ends I need to buy and do they require crimping on or just slotting on to the wire.

Thanks for your help

Tim
