I have 3 questions.
1) I'm stuck here idk how to crimp on something new to connect it to the wiper motor? help

2) Isn't there supposed to be something covering that? Like a black rubber boot? idk. Because the hole is open and water can get in easy.

3) Trying to connect the wires from the trunk and the roof of the car but the trunk connection dont fit how do i approach this

I'm really confused i never worked with any wires before.
