Seats wiring loom c63

[jghazanfar]

I have bought a 57 plate Mercedes C200 CDI. The previous owner put C63 seats and door cards in. The seats are not connected and the previous owner says i need a wiring loom. I have been to Mercedes and they say the need a chasis no and part no. of a C63 with the same seats. A friend has suggested just putting in the “mechanical frame” of the standard seats.
Is there a mechanic who can sort this out for me i live in postcode BB9 ? What sort of costs are involved ? Has anyone done this before ? my email ([email protected]) phone no (07503149536)
