Hi Guys
Thanks for the info but it raises more questions.
1. Where is the K8 relay and what does it do.
2. Where is the Blue 2 pole temp sensor and what does it do.
3. Why does my MB factory wiring dia for that car show the K9 relay coil being grounded by the push button unit to actuate it and thus turning on the fan in front of the rad, as it stands now the HP swt does turn both the front fan and engages the clutch on the engine fan.
Is my wire dia wrong?
Thanks Chuck
