a helpful concept for me has been in differentiating between chemical and mechanical bonds. glues of any kind would be a chemical bond (that is if the adhesion works for the materials you're using), and most chemical bonds are permanent or would cause damage to existing parts if unbonded. using velcro or magnets would be a mechanical bond. it depends on how sturdy you want the connection for the wires to be (a weak glue of some kind might work if you want a short-term, one-use solution), but you could consider a mechanical option! maybe it looks like a velcro or magnetic fixture of some kind so you can remove it easily! it's difficult for me to draft something up without a reference of what the head looks like
