This pass-through harness is required for J1939 programming when using BenchForce PowerBlock switch assemblies.
The 10 pin connector end plugs into any J1939 ECU programming harness with 10 pin connection.
The 10 pin connector end may alternatively plug into Y-Splitter harness. Y-Splitter harness is only necessary when adding an additional ECU on the bench.
- The 24 pin connector end plugs into any of our PowerBlock switch assemblies.
