You will need this Cable to use your Cat Com adaptor to hook up to Cat Hiway (Truck)
This is a J1939/11 Truck In-Cab Adapter cable. Some CAT equipment will need cable to properly hook-up. The black end is typically what hooks up to a truck, and the gray end hooks up to off-road equipment. Same as CAT Part # 157-4829.
This cable is made to order and has Genuine Deutsch 9 pin Plugs so it is as good as if not better than the Genuine Part .
