I`m trying to make my seat heating like OEM, but until as far as i now heating mat is sold with the leather. So i have to find heating mat nearly close to the OEM. I need some help from heated seat owners to measure their seat and post the measurements. What exactly i mean.
This is the wiring heating wiring looking at E56a driver`s seat backrest heating. I need to now the resistance of heating element and the temperature sensor. Simply unplug the connector X13987 or X13985. this is how it looks like.


The measurements are between pin 1 and everything else.

I hope some one will help me!!!
