Is J3 on the schematic the pin header with the link attached ?
Yes that's correct. Removing the jumper will break the power (VCC) supply to the backlight.

Can you also advise a part number for the 4 core lead that is shown in the photo's ?
It's the following 4 way anti-reverse cable: ... cable-30cm

If you don't need it to be anti-reverse there are the following alternatives which can be stripped into 4 way pieces: ... cable-10cm ... cable-pack
