Stick wire harness is loose

My friend’s stick that he has been using for about 1 year now has a problem

The harness here is very loose when plugged up. It works fine when plugged up but after a bit of use it becomes loose again. Apparently we accidentally broke the way of securing it I believe when we modded it in the first place, but regardless is there a way to securing it now?

Sorry on any terminology as I’m not sure what the call the 4 wires besides a harness.

you could order a wire harness from if you wanted, they pretty cheap lol

Hot glue gun it.

just for clarification

I circled what is getting loose to make sure I don’t cause a misunderstanding

Like he said, buy a new harness or hot glue gun it in place.
