12V PowerBlock™ Switch Assemblies
While all of our PowerBlock™ switch assemblies can be used for OBD-II and J1939 programming, our PowerBlock IV switch assembly is unique in that it contains a top-mounted momentary switch for Cummins ROM boot feature. ROM boot wiring is seamlessly built within our line of Cummins ROM boot programming harnesses. Because of the included ROM boot support, we recommend the PowerBlock IV for customers shopping for a J1939 bench programming solution.
In some cases, with the exception of Cummins ROM Boot programming harnesses, J1939 support will require our J1939 pass-through harness. We encourage you to contact us with any questions about our BenchForce™ line of products.
