I have a wiper switch from a car that has a rear wiper setup, the vehicle I want to put it in does not have a rear wiper setup on it, will it hurt to use this switch with my car not having a rear wiper. I assume that its all prewired and just a dead end terminal at the rear and will not make a difference, I just wanted some input if anyone had a definite answer.

 

I don't have a definite answer, but i agree with your logic because far as i know the wire harnesses in the back were the same

 

should not be a problem to install
