I added the rear heated seats to my 23 XLT super duty.

Pronebeta, great job on installing everything. Do you have any tips on where and what the harness connects to in the center console? The easiest parts to install are the rear seat pads, rear harnesses, and heating modules.

The center console harness was o ly needed for doing the factory switches int he console. My console harness did not have the wiring for that switch.
I brought my console inside to do 'bench work'. Even then you will probably scrape a couple knuckles replacing it. Jesse and dolsen were big helps in this effort and inlearned a lot from reading their posts. The console wiring harness connects under the hvac controles on the passenger side.

The heated seat harness connect to the large white connector next to the driver side C-pillar

Thank you! One of the harnesses ordered has a bunch of loose pigtails I do not know where they go.

Which harness is it, can you provide a pic?

Of course you did. It's probably easier for you to list the parts you don't put into your vehicles.

Have you done some MCS seats in it yet?

Not yet.. debating on sticking with the cloth seats or going memory like I did in the F150. I added heated to the cloth front and rear. Not sure if I want to go all out on the f250 yet. I may though

Will it accept a 150's DSM? Might be a nice little seat project in your future. I got all of my donor parts from a wrecked platinum.

You will go all out though and I can respect that

My mistake! Veiwing the harnesses on line, the harness that showed a picture with the part number MU2-Z14S411-MA not MU2Z-14S411-SA for the rear seat pigtail

You’ll need the wiring diagram to figure them all out

Does anyone with rear seat heat have a picture of how the module attaches on the back seat? I see a void space in the foam that makes sense, but maybe there is a bracket missing or ive gotten the wirring anchors wrong.
Component Location View doesn't really show it and theres no pictures I could find on the webs.

There is a bracket and some screws. I had a pic of it but deleted it off my phone apparently. I’ll see if I can find the part numbers for the bracket and screws later today

I just saw this.. You still have them? Yes teh DSM is the same across the two different firmware.

Technically the seats are different part numbers.. THe Super Duty doesnt have the Occupancy sensor like the F150

I’m not sure who you’re asking, but I have a 501A. I think all lariats have the same floor harness. There’s another member on here with a 510A lightning that doesn’t have factory heated rear seats and he added them. He also has the same floor harness that had the C pillar connector

Hi Dolsen! Just following the thread and wanted to know how you worked around the backordered MU2Z14S411SA wire assembly. I am getting ready to order the parts through different dealerships. It seems like everyone has a different discount for each part. The last wire assembly is going to be a pain to find. I checked a lot of pick a parts here in New Mexico, but no luck with one with heated rear seats.
