working out wiring in for new light fitting

[ban-all-sheds]

OK - how would you fix the choc blocks to the light fitting - with insulation tape or something else like glue?

Neither - drill a hole in it and use a small machine screw & nut.

I assume I use the heat resistant sleeving on the single 'extension' wires going into the light fitting

Yup.

(I will have to buy some more of the stuff as it got wasted in my attempt to fit all the wires into the light sockets)

What do you mean it got wasted?

It got wasted in that I originally attempted to fit the heat resistant sleeve around a number of wires and it was a mess...
