thanks for the info... I called up BMA, but unfortunatelly it seems that based on the VIN # for my car the wiring harness is different... p/n 202 440 79 05 - $760.00
it seems I have a newer version c280... anyhow, I'm trying to confirm the part # before I decide to order.... can you please tell me where to look in the engine bay for it... I lifted the computer cover up, but I'm not sure where the engine cover plus into as there are 4 big harness plugs.... any pics would help a lot, thanks again...
