You should get that pigtail with the pump. I just connected the black to ground. Use a ring terminal and screw it to the frame. Use the add-a-fuse to tap into the fuel block. I think you will need a small piece wire and two splices to cover the length needed. Find a fuse that is hot only when the ignition is on. You will need to cut a slot in the fuse block cover for the wire to slip into.
I used a length of clear tubing going into the IC core. You can see the coolant moving and tell how many air bubbles there are.
