Description
Cummins 850-876 Adaptor
Pinned out for all variations from CM850 through to CM876 ECM. The adaptor does accommodate boot mode. The adaptor needs to be used in conjunction with a Base Cable to produce a complete and functioning bench harness for the CM850-876 ECM. The completed harness allows for the standard diagnostic and programming software to be used while on the bench or still in situ.
If keeping the ECM in place disconnect the engines battery ( not just isolation switch ) and disconnect all other plugs to the ECM.
