WOW, this is some HWare hacking 
It is now clear that I have to gently tear off the white plastic from the Mobo, then place the ribbon cable init, and replace the whole assemblage.
You don't have to rip anything off your motherboard. You have taken the wrong end of the stick, unfortunately. :-o
If the cable is not damaged then all you have to do is slot it back in.

White connector
The white connector has two tiny white tabs inside it on each side.
When you pull them up slightly they allow the ribbon cable to slot in easily. Afterwards just push them down again for a tight fit.
I hope that dodgy diagram clarifies my point :-)
