Update Your Wiring Harness
Painless Pro-Series Wiring Harness Kits come complete with all of the items you need to wire-up your pro-touring or custom project. Each wire harness contains enough length for each circuit so you can route and hide your wiring however you want. New built-in circuits and included connectors/terminals allow for customizing into a direct-fit harness. LED ATC bladed fuses replace glass fuses, and will light up if blown. A 6-gauge charge wire and midi fuse can handle the highest amperage alternators, and the front and rear ground harnesses make grounding lighting circuits an easy task. Most harness kits contain GM connectors and terminals, insulated and non-insulated butt splices, heat shrink, grommets, cable ties, ground straps, and cable tie clips.
