We will now get the black connector for the power plug and install the wires into this plug. If you look carefully at Pic 1, I am holding the wires the way they will insert into the plug.

There are tabs on each side of the metal plugs and they are inserted with the tabs facing the long flat side of the black connector. This is how the wires are being held in Pic 1 and how they will insert into the black housing.

The black wire will go on the side of the black housing with the clip on it. THIS IS IMPORTANT as polarity DOES matter!

You will insert the red wire on the opposite side of the clip as shown in Pic 2.
