10 The raw material for the pigtails to run and ground the lights: 12-gauge automotive wire, female spade terminals, two sizes of heat shrink, and a butt joint. I used the butt joint to make the pig tail, inserting the stripped ends of two wires in one end, and a single wire in the other. Although the joint comes with heat-sealing material on it, this tends to get torn in the crimping process. I invariably seal it up with heat shrink—and remember, slide the heat shrink on the wire before crimping the terminals into place.
