Supporting Documents

Our modular ECU benchtop programming harnesses provide a connection to the ECU (Engine Control Module, Transmission Control Module, Body Control Module, or any other on-board vehicle ECU) and a connection to one of our switch assembly pass-through harnesses.

This switch assembly pass-through harness is for use with our GM ECU programming harnesses. Simply connect any GM ECU programming extension harness into the 10 cavity female connector and the 16 cavity female connector to the switch assembly. 

To power more than one ECU on the benchtop, a Y-Splitter harness is required. See EFI# 100-01031.
