Wires in the back of the product March 19, 2019
Reviewer: Marty  
The red and black wires coming out of the unit did not align with the hole in the wall from the old unit.  Had to drill another hole in the wall to line up with where the wires come out the back of the unit.  Not a big deal, so gave it 4 stars.
