Yep thats what I did. Then there is no need for the cable ties later on.

Drill out the original knob that goes in there. Get the cable through before the soldering step. Then you can just pop it back in.

Acutally if you have a set of drills you can carefully drill out the original button and thread the wires through it before soldering. Then there is no need for the cable ties.

Job done….With a smashed screen remember to apply clear scotch tape to hold the screen together. Continue to heat the remaining stuck shards when the main bulk of the glass comes out. Pick them out carefully, and not to raise the gasket. Use a strong magnifying glass. the ifixit heat gel pack and tweezers helped me. Ensure that all tiny bits of glass have been removed form the body. Just turn it upside down, give a couple of gentle taps with something plastic. Pick out if necessary, taking care around the components. For a smashed screen, needs a good hour or more.

Great instructions. If you're going to embark on this fix you really need to observe the suggestion about being patient. Some zoom pics would help too. I got a new glass that came with all the tools and the adhesive went all the way around. Keeping the lower buttons down can be tricky but again, patience is the key. And have the right tools. No probs with the LCD. Just need to be careful. thanks again.
