Heated Seat Question

2023 CX-5 Carbon. I don't have a wiring diagram and would like to ask before I take the seat out to discover. My desire is to disconnect the bottom cushion heater and keep the backrest heater. Question is: are both heaters wired together or do they have separate plugs where I can disconnect the seat cushion heater? Thanks for anyone willing to offer an answer.
 
From my wiring diagrams, it looks like the 2 panels are hard-wired in parallel. No separate connectors. Sorry.

RedBaron, thanks, now I know I will need to separate the circuits. Looks like three heating units? Guessing one for the seat and two for the back? May as well add a switch in case I want it to work again. Thanks, Tom
No, just 2 heaters, the third thing (rounded outline) is a temperature-sensing thermistor. I'm not sure where that's located, but it may be on the bottom cushion/element, in which case it would be dangerous to disconnect that bottom element!

All in all, this is a very bad idea. It could disrupt any current sensing in the controller and have unknown effects. If your butt is getting too hot, just get a seating pad to insulate it!

Ohhh, thanks again. I'm sure it will be more obvious once I lay eyeballs on whatever wires of connectors are there. Probably more trouble than the benefit I will get but sometimes I just get bored and want to fix or change things. I'm ancient and need things to do sometimes. haha

You replied as I was editing my response. Please reread.

Just say no! :)
Very good point, with all the sensors and electronics at the very minimum it could turn on some annoying warning light that would be more bothersome than the seat too hot. Thanks for that warning. I'll just live with it. Thanks Again.

i think this thermistor may be on the lower seat cushion, rear right side below the sticker.

from what I recall each cushion (seat and back) has its own connector which is plugged under the seat. Its been a while since I dissasembled my seat so my memory is vague.

See if this helps. Removing the seat is easy. 4bolts just disconnect battery first.

You can trace the black (not ribbed) cable from the seat cushion and where it connects.

There are two connectors in 2021+ but the way it's wired, unplugging 0913-202 cuts power to the seat back side. Maybe it's possible to unplug both 202 and 203 and move harness to plug directly to the seat back side B,D,C, see picture.

Thank you MZDCX5, I don't have seat ventilation. I appreciate the time and effort you put into this.. If I decide to continue along this line I think I need to pull the seat and do some trial and error without destroying anything, haha. Thanks again, Tom
