Hello Roger. I don't have that particular Miller kit, and I'm sure Miller would promptly respond if you asked, but I'm almost certain the answer is yes.
The extra contact pairs allow you to cut off sections to make smaller panels. As long as you have one contact pair remaining, the entire panel illuminates. As shown below on a scrap piece of blue EL panel (not Miller), I don't even use the provided contact pair but scratched off the insulation to the 2 layers and clipped on. Hope this helps...
