CAN communication errors MX-13 epa13

When referring to the 'green' wire, was it part of the 4 main wires on the connector for power/j1939 to the VGT?... or was it a single green wire that was by itself, coming from a single sensor at the center of the turbo housing?.

If it was a green wire that was coming from the center of the housing, then that is the speed sensor. Repairing it yourself, if it is damaged, does little to no good. It is an extremely high frequency signal, and splicing into it will make for far less than optimal path for that signal. The whole sensor needs replacing if that is the case.
