I just got my new injectors , precision turbo, PFU 042-525. I went to install them but the electrical connector on the injector has the key way in the center. The clip on the engine, JDM B18c, has the key ways on the upper left and right corners. Can any one explain this? Are all Honda/Acura high impedance clips keyed the same? The P/N is correc t for high imp honda style injectors.
