Compatible with neutral start systems, the harness includes a jumper plug for easy disconnection and wiring to the transmission’s neutral safety switch. Ideal for mechanics and fleet operators, this high-quality harness ensures reliable power and starting performance for custom builds or fleet upgrades.
