Awaking This OLD A$$ thread hopefully some with a 2005+ C55 can help me out! Ok here goes. My car never came with heated seat! But I got a deal on some C55 Front & Rear Seats which I installed during the month of august. Work out GREAT just had to rewire the sockets under the seats so that the adjustment functions can work. I didn’t hook up the heated seats until two weeks ago. I purchase the Wire harness from the dealer. The harness has five ends
1. For the drive side fuse box.
1. For the center console control.
1. For the driver seat.
1. For the passenger seat
1. Ground Wire.
Under the C55 seats has a 2 Pin Connector & Different Shape see picture 1

But the Wiring harness has a 4 pin Plug & Different Shape see picture 2

So what I did until I get the correct Plug I cut off the plug and installed some radio shack Plug Picture 3

Connected up everything and HEATED seats are working but I notice only the Back Rest Gets Hot in both Driver and Passenger Side.
So I wanted to know if the Seat/”A$$” Part suppose to get Hot As well.
So please let me know anyone who has a 2005+ C55 some pictures of your wire harness & plug would be nice too!! Thank you!

Yes. Advans Please check for me :-D thanks!

i looked under the seats of a couple of other Cars that has the Heated seats they all have the 4-Pin Connectors i am guessing 2 of the Pins are for the Backrest and the Other 2 is for the Buttom Seat and since the C55 seats i got only have 2-Pins they are just for heating up the Backrest.. which is Strange.. but hey am kool with it.
