Plastic Tabs Holding Injector Harness on Throttle Body July 05, 2012, 12:34:03 PM Rebuilding my Throttle body. The injector harness tabs used to lock the harness to the injectors is old andIMO plastic is brittle. Question: Anyone know if I remove the tabs whether the harness will stay attached to the injectorswhile vehicle operating. (Don't want these tabs breaking loose and being sucked into the engine).
