How do I fit a cable to the black connector that is used to power the MkII DL1?
Select a small, flat bladed, screwdriver.
Insert the end of the screw driver into the square aperture, underneath the hole into which you wish to fit the wire. You will need to push the screw driver in quite firmly.
With the screwdriver still in place, insert the stripped and tinned end of the wire.
Now remove the screwdriver, leaving the wire to be gripped in place.
