### Supercharger Clutch
* F14 removed
* R80 jumper added on back
* High-current MOSFET like for example VNB14NV04 is soldered on Q6 instead of IGBT
If you want to control the clutch on a Mercedes supercharger, some hardware modifications are required. The following modifications will result in pin F21 being able to control the supercharger clutch:
* F14 must be removed
* R80 jumper is added on back of PCB
* Remove IGBT from Q6
* Solder high-current MOSFET (for example VNB14NV04, VNB14NV0413TR) instead on Q6
