970579 OEM style main wiring harness, complete set. XL

This complete main wiring harness set is the ultimate solution for a total electrical overhaul on 1986 to 1990 XL Sportster and XLH models. Unlike basic harnesses, this comprehensive kit includes the wiring for the handlebars, taillight, coil, and regulator, making it a truly complete replacement. It is designed to match OEM 70135-86 and 701135-86, featuring color-coded wires and pre-attached ends for a factory-correct finish. This set is perfect for full restorations where you want to replace every inch of old copper. While it is built for stock bikes, some sub-models might require minor adjustments during installation. It is the most thorough way to ensure your Sportster's electrical system is as good as new.
