What is the part number for the EC21 connector on the G4KF engine?

The EC21 (G4KF) connector pair is KET_040III_38M_W (male) and KET_040III_38F_W (female), a 38-position connector. The same part numbers are shown for the EC21 on the G6DA engine.

How many pins does the EC11 connector have and what are its part numbers?

EC11 (G4KF) is a 23-position connector: KET_050_23M_W (male) and KET_050_23F_W (female). Pin 6 on one side is marked with a star (unused/keyed position).

What connectors are used for the ignition coils and injectors?

CLGIG (ignition coil) uses KUM_KNMWP_04F_Gr with mating KUM_PB621_04120; CLGINJ (injector) uses KUM_NMWP_04F_B with mating PB621_04020_C01. Both are 4-pin connectors numbered 1-4.

What is connector EF11?

EF11 is a 22-position connector pair, AMP_090III_22F_W (female) and AMP_090III_22M_W (male); several cavities are marked with stars indicating unpopulated positions.

Which engines does this connector page cover?

The page shows connector variants labeled for the G4KF and G6DA engines (e.g., EC11(G4KF), EC21(G4KF), EC21(G6DA)).

This is page CC-1, 'Harness Connectors (1)', from a Hyundai factory service manual electrical/connector reference section (drawing code EBKCC9001AN). It illustrates mating pairs (male and female views) of engine and body harness connectors with their pin cavity layouts and manufacturer part numbers. Connectors shown include: CLGIG (ignition coil, 4-pin, KUM_KNMWP_04F_Gr / KUM_PB621_04120), CLGINJ (injector, 4-pin, KUM_NMWP_04F_B / PB621_04020_C01), CLGOCV (oil control valve, 4-pin, PKD_GT150_04F_Gr / CR04M044), EC11 for the G4KF engine (23-pin, KET_050_23M_W / KET_050_23F_W), EC21 for both the G4KF and G6DA engines (38-pin, KET_040III_38M_W / KET_040III_38F_W), EE11 (26-pin AMP connector), and EF11 (22-pin, AMP_090III_22F_W / AMP_090III_22M_W). Each drawing shows pin numbering orientation for both connector halves, which is essential when probing or repairing wiring — for example, when tracing fuel pump or engine control circuits. The G4KF (2.0L turbo) and G6DA (3.8L) engine designations indicate this page applies to the Hyundai Genesis Coupe, consistent with the uploader's album of Genesis Coupe wiring diagrams.
