Several new terminal types were introduced as well (TPX50-50 and TPX120). With three different types of terminals required, new crimp tooling was necessary. 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"text-decoration: underline;\"\u003eIMPORTANT!
