i connected cable to my cooker took the cover off the box on the wall and it has the 3 wires red,black and g&y there is no holes to put the cables in. i dont understand this. the fitting looks old
if you mean the brown plastic plate then yes you do need it. If the screw goes into the white plastic moulding then a "self tapping" screw or possibly a chipboard screw will hold it. You might find the same size in a discardd plug.
If you haven't got a jar of old screws then you can take the remaining one to your hardware store and get one the same length and thickness. Get yourself a jar for odd screws, every handyman has one on the shed shelf
If you get in real trouble, you can buy a new cooker connector plate for a few pounds. If you get the chance, have one in two pieces (where the metal part with the terminals screws into the back-box first, and the white plastic cover is separate)
