So, I just bought an Alcantara interior for my car, because my Dove Gray interior is pretty beat after the fire. However, the Alcantara interior is not heated, while my car is. I want to save this feature if I can, but it's not the end of the world if I can't. I have donor seats with heat and lumbar, and I will be trying to retrofit both into my Alcantara seats, and I hope to get Sean's help here, whenever we can both make time for it.
Anyway, this is the DIY I was using for my info: http://forum.e46fanatics.com/showthread.php?t=341242
Interestingly, the entire DIY is him doing what my car already has done, that is, the wiring part. He paid a shop to fit the elements into his seats, which is where I need more info. Where exactly do these heating pads go? Do they go between the seat leather and the cushion? Do they go behind the cushion? How can I access this part of the seat? No idea.
I would love to get some info from people who have dug into their seats. This DIY will be a little ways out, but I want the info so I can start planning for it and whatnot.
