Overview of Design Background This is a update to wiring harnesses used on QSK 50-60 Industrial application (D283038CX03, D593007CX03). Braid design with brace enclosure proposed as a replacement for current tube design. OEM connections and interfaces will not be changed. Cost reduction, as Cummins ownership, we will be in better position to dictate the cost by sharing drws with multiple suppliers Value addition eg can be done with having single schematic released in PLM which can be used by crossfunctional team. To make harness components common Cummins Confidential
