Just collecting parts to retro fit rear heated seats in my ML63, anyone done this?
Harness is the biggest problem, where does it plug in?

Any help or pictures please.

thinking of the same project. Does anyone know how to remove the seat covers from the rear seats? I want to take the seat covers off to see if i can only fit OEM heating pads or is an aftermarket product would be a possibility but the bottom and back portions look solid, could not find any instructions online as well....

Hi, Yes The backs are clipped on, not got that far but the 3 harness are on order.

Got some progress on this now with plug and play harness made up.
I could do with a picture with the seats up to see the wire route, anyone?

We have a local shop add 2nd row rear heated seat with aftermarket components - switch control installed B pillar - $800 all in - have no idea on OE component install - haven't priced out those components.

This info should help if you are going the OEM route. The rear SAM is located under the rear seat.

Thanks for that, how do you get the drawings to pdf from star?

jrsmith_68

I use WIS. I could print from STAR too. The only printer I have installed is the PDF Writer so when ever I print anything it goes to PDF.

Can you share the photos of the switch and its' position as well as the route of the wires when seats are in raised position?
does anyone know where can an an auxiliary power can be tapped in to to power the aftermarket heating pads?

Factory switch and wire from rear control module under the rear seat, its 4 wires in there and power from the pre fuse under the seat next to the battery

Thank you for starting the thread Zenman

I had to replace a 2nd row ( rear ) seat cover, valet had destroyed seat leather with over cleaning, anyhow, Can't replace just one seat, Rear seat covers came with heating elements.
I might as well take on a new mission to have them connected. Front heats are already heated.
I need the cable wiring and rear seat heating modules, This can be found somewhere or ordered.

What I am desperately short of is the layout of the modules and wiring cables, where are they fixed under which seats and how, how many modules would I need, one for each side., and the cable that runs from module to the console.
I think, you can tell the level of my expertise and that I do need to be guided. I can do visual to a certain point and get someone who can read to follow thru with the rest of the cabling. Would I need individual pcs of cabling or or a harness. I am in the dark here without any pictures.

What I really need is pictures of the modules and cable layout beneath both rear seats so I can follow suit

Does anyone know, if I need to replace both rear and front heating / AC consoles.

Could someone please share pictures of the seats layout.

Can someone please shed some light on this, I appreciate that very much. Thank you so much.

Hi. I’d like to give this a try on my 2014 ML350 W166. Has anybody completed this project successfully? Perhaps you could give a summary of the parts and steps necessary? Thanks for you help!
