Working back on the red and black power wires, you will get the two crimp on terminals for the red and black wires.

The crimps have 2 sets of tabs sticking up from them. One longer set at the back of the crimp, and one on the inside that are smaller. You will want to place the bare portion of the wire inside the smaller tabs on the inside, while having the coated part of the wire inside the longer tabs.

Using a crimping tool such as a PA-09 crimping tool, use the 1.9mm crimp slot to crimp and secure the bare wire part on the inside tabs as shown in Pic 2.

Repeat this process on the red wire as shown in Pic 3.
