  • Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

Good afternoon, so I replaced the engine on my 2015 Hyundai Genesis 3.8 sedan. I can not find the electrical connector that connects to that sensor. The sensor is behind the passenger side cylinder head right above the thermostat housing. It has a part number 3C100 on it and it goes where I highlighted with red. I cannot seem to find the connector anywhere. Anyone please help?
