Connect Limpaparabrisas direct to battery

Hello good and thank you in advance for help. I am riding a small car for my daughter and I want to equip it with the engine. I will ride it with the engine of a windshield wiper but I have no idea how to connect it directly to the battery.

I have achieved one but it has 5 cables, red, black, purple, white and gray. The white and red engine directly enter the clean engine. Let's see if someone can give me a hand to install it and tell me if I should take into account something for security, that is, I do not burn.



Thanks for the help.
