    • When reinserting the two exposed wire ends into the green terminal:

    • First, compress the wire ends so they are relatively flat.

    • Then, insert each wire end into the green terminal, noting the polarity of the cables: the black cable should go into the upper slot, and the white cable should go into the lower slot (as shown in the third photo of this step).

    • Finally, gently tighten the screws until the wires are secured.

    • Your replacement controller may not come with a power switch. If so, transfer the power switch from the original controller to the new one:

    • Unscrew the two Phillips screws on either side of the switch.

    • Reattach the cables from the new controller to the switch, making sure that they go back on the same sides you found them.

    • The white cable goes on the side labeled with the number 1.

    • The black cable goes on the side labeled with the number 3.
