For the red wire on the towing socket please don't leave it like that.
Just use a short piece of wire to bridge it
What he said, that's a fire waiting to happen!
Cut the wire back and re strip the end and put it in the hole you need and just cut another short piece and strip both ends and use that as the link wire. Try to have it so the sheathing on the wires is just below the surface and you don't have exposed cores above.
By essentially halving the number of strands in the wire you create a point where you get high resistance and so heat then potentially a fire. Also, I cannot tell from the pic, if you have the sheathing cut back a long way the exposed cores may touch one of the other terminals and short and cause... you guessed it, a fire or at least melty wires.
