970551 OEM style main wiring harness. XL, XLS

For the 1981 XL Sportster and XLS, a reliable electrical system starts with a solid main harness. This MCS replacement is built to OEM specifications, serving as a direct substitute for part number 70006-81. It features color-coded wires and pre-attached ends, which is a lifesaver when you are trying to keep the restoration looking factory-correct. This harness covers the main chassis but does not include the handlebar, taillight, coil, or regulator wiring. It is designed for a stock setup, though some sub-models might require slight modifications during the install. Replacing a tired original harness with this unit is one of the best ways to prevent roadside breakdowns and ensure your Sportster's electronics are up to the task.
