Enhance diagnostic flexibility in your Peterbilt or Kenworth truck with the Kustom Truck J1587/J1708 Datalink Jumper Harness, designed to bypass the data bus block and connect directly to the OBD connector inside the dash. This jumper harness is tailored for NAMUX3 generation Peterbilt or Kenworth trucks with engines that utilize J1587 as the primary diagnostic communication protocol, such as Caterpillar engines, Cummins N14 or M11 engines, or Detroit Series 60 engines. It may or may not be required to communicate with the engine ECM diagnostically using OEM engine software, depending on your truck’s configuration. This 1-piece jumper serves as an add-on to the GEN2 dash jumper PN: 99906011 and, when combined with dash jumper PN: 99906004, forms the complete GEN2 dash jumper assembly. It’s ideal for customers who already have a 99906004 dash jumper but need to bypass the bus block and connect directly to the OBD connector for streamlined diagnostics. For compatibility confirmation, contact Kustom Truck. Upgrade your truck’s diagnostic setup with this precision-engineered jumper harness, crafted for durability and performance.
