Hello all,

I came across a lovely S500 2003, loaded with a bit of options but also loaded with a bit of problems, which is quite normal given the cars age.
Spent the whole night on internet looking for SCU (seat control unit) wiring diagram/pinout but could not get anything useful.

The unit itself is following: Temic 7654 (220 820 12 85)

If anyone can provide wiring diagram/pinout of what each pin means on each connector it would be greatly appreciated.

Thank you.

Do you mean the door control module (Dcm) which is the power seat switches on the door ? Door control modules are a high failure item and easiest to just swap with one from eBay

Nope, the module that sits under the driver/passenger seat.
For DCM i got the wiring and pinout but it doesnt help me.
