Wire to plug in driver door

So, the black wire in the top there is causing me not to have my windows or locks or mirrors. It does not want to stay in the little hole for the prong that goes into the door. What should I do to keep it in there? It has all that sticky goupe in there.

Thank you in advance. 3D92E8C6-80B6-4D86-AB37-6EAF90CE8647.jpeg
