The fuse harness provides power from the battery box to the main engine harness on Peterbilt NAMUX2 or NAMUX3 trucks. The extended length harness is for use when the battery box is located either on the passenger side under the passenger door or on the driver side behind the cab.
NAMUX2/3 electronics are typically found on 2008 and newer year model Peterbilt heavy duty class 8 trucks such as 389, 388, 386 and 367. If you are uncertain of your exact chassis electronics please call for fitment confirmation.
NOTE: The extended fuse harness is 12'8" in overall length.
