This Engine Control Module Bench Harness 24-25 GM E42 6.6L L5P is used with our BenchForce PowerBlock™ to program GM E42 Global B ECMs.
Brought to you FIRST by BenchForce! The GM E42 ECM introduced a new type of Molex ECU header and its mating connector. Several new terminal types were introduced as well (TPX50-50 and TPX120). With three different types of terminals required, new crimp tooling is necessary (greater than $6k expense). This genuine Molex 93 cavity ECU connector requires a dress cover to lock the lever in the seated position. Using SLS printing technology, we've manufactured our own PA12 (nylon) dress cover that is highly ductile while rigid in its use.
IMPORTANT! The E42 ECM is Global B platform and requires a 3rd party unlock service to communicate on the bench. BenchForce does not offer ECU unlock services.
