Golf IV: Connecting Universal Seat Heating Mat - 4 Wires, Original System, 2-Cable Bundle

Hello, I wonder if someone will answer? I have a golf 4 I changed the heating mats in the driver's seat. The backrest and the seat. These are mats that have two cables in a bundle. The car has an original seat heating system. And there are 4 wires on the ankle. Two thin and two thicker. Rociel I have an old ankle bundle right next to the ankle chair and I have a problem because now I do not know how to connect it. For now, I have only connected the thicker ones and of course it does not heat up, but I have no idea what to do with the thinner ones. Is it a bridgehead ???.

I bought this mat:

Plug the meter into the cube and look for which pins the voltage appears after turning the potentiometer.

Hello. Two thin wires are connected to the thermistor located in the bottom mat.
Without it, the controller, not "seeing" the temperature of the mat, will not give voltage to it.

And now it works. As you said. I took out a thermistor from the old mats. And it worked. Closed topic j
