Hyundai Genesis Coupe 3.8L (G6DA) MFI Ignition Coil Wiring Diagram SD313-10
Wiring diagram showing ignition coil and condenser circuits with grounds for a 3.8L MFI control system.
This document is page 2 of the MFI (Multiport Fuel Injection) Control System wiring diagram, sheet SD313-10, for the G6DA-GSL 3.8L V6 engine. It shows the ignition coil circuit: power comes from the Engine Control Relay (referenced on SD313-9) through the 20A IGN COIL fuse in the E/R (engine room) Junction Box RH, then through joint connector JCL81 to all six ignition coils (connectors CLG18-1 through CLG18-6) and two condensers (CLG19-1, CLG19-2). Feed wires to the coils are P (pink); control-side wire colors are W, B, Y, L, R, and G. Each coil's control wire runs to the ECM connector CLG-B: pin 24 (Coil #1), 49 (Coil #3), 74 (Coil #5), 98 (Coil #6), 99 (Coil #4), and 97 (Coil #2). Grounds go through GLG01 and GLG02, with a reference to Ground Distribution on SD130-8. Photo callouts (PHOTO 19, 24, 26, 28, 32, 34, 36) point to connector location photos, and connector CLGIG links the coil ground/shield circuit. A reader can use this to trace ignition coil power, control, and ground circuits and identify the correct ECM pins and fuse for diagnosis.

Frequently asked questions
- Which fuse powers the ignition coils on the 3.8L G6DA engine?
- The IGN COIL 20A fuse in the E/R Junction Box RH, fed from the Engine Control Relay (see SD313-9).
- Which ECM pins control each ignition coil?
- ECM connector CLG-B: pin 24 = Coil #1, pin 49 = Coil #3, pin 74 = Coil #5, pin 98 = Coil #6, pin 99 = Coil #4, pin 97 = Coil #2.
- What are the connector numbers for the ignition coils?
- CLG18-1 through CLG18-6 for ignition coils #1–#6, and CLG19-1 / CLG19-2 for Condenser #1 and Condenser #2.
- What wire color feeds power to all the ignition coils?
- P (pink) wires from joint connector JCL81 feed pin 1 of each ignition coil connector.
- Where is the ground distribution for this circuit documented?
- The diagram refers to Ground Distribution on sheet SD130-8; grounds shown here are GLG01 and GLG02.
