Hi all,

This is my first post, I'm excited to be part of Rennlist. My first question: Does anyone know which wiring loom contains the coolant level sensor wire? The level sensor on my 2008 C2S is not plugged in and I can't seem to find it anywhere. I've been digging around my engine bay and can't find where it branches off from. If anyone knows or can trace the line on their car, would be great. Thanks in advance!
