[Bellcon]

Have a 2016 Slv75-s that at first started having issues with Dpf black smoke it ran rough. Turned off the #4 ram better. Changed injector 4 started but filled the entire ski white. Injector 3 and 4 omed bad. Mechanic said new wiring harness. 1. Where can I purchase a cheap harness . Could there be another problem ?

Have new injectors been programed into the ECM?

Why would he think it needs a wiring harness if #3 & #4 injectors ohm bad?
