We are having difficulty connecting our switch to our CPD. I have 2 red cords and a black. The black cord doesn't have a crimp do I need to purchase a crimp if so, could someone send me a link of what I need to purchase. https://www.pitsco.com/TETRIX-RC-Switch-Kit

I have included the link to the item purchased. I di see this as well in the wiring guide. But, I am still confused. Thanks for any help!
