Over decades of exceptional law enforcement and emergency vehicle upfitting, Defender Supply learned that internal electronics are only as good as the wiring harness that connects them. Each combination of vehicle, equipment, and controllers called for a bespoke wiring harness to make everything run smoothly. For years, Defender Supply painstakingly created each of these wiring harness by hand in order to fulfill the needs of each upfit. Then, in 2019, Defender Supply streamlined their process by investing in a robotic wiring harness machine. This not only created the exact harness configurations needed in a fraction of the time, it also created harnesses with more precision and ease of use!
