For a truly professional installation, many XJ owners replace the cheap push-button switches that come with light kits with factory fog light switches from a junkyard donor. If your XJ did not come with fog lights, you can still add the factory switch panel and wire it to control your LED lights . The factory switch uses a purple wire for the 12-volt trigger source, a black wire for ground, and an orange wire for dashboard illumination . One clever XJ owner bypassed the aftermarket switch entirely by connecting the relay trigger wire to the blue wire behind the driver-side headlight and installing a jumper in the fuse box . This method allows the light bar to operate independently without the ignition key on—perfect for campsite illumination—though you must be careful not to accidentally drain your battery .
