Retrofit Heated Seats - A Complete How-To

[Con.mc123]

Why buy the Kufatec garbage? Why not buy the Erwin connection? Seat heating uses a total of four wires. The airbag is separate anyway, a yellow connector, and the third two-pin connector is for the seat belt control.

These are all the wires under my seat. Sorry for the bad pictures, screenshotted from a video.

Honestly I bought Kufatec because everyone seems to be using it. Didn’t know Erwin connection made/ sold something like that - have you got a link so I can check it out?

Erwin (the website) doesn’t work great from where I’m from…

Yea I know that, it doesn’t let me type in my VIN in my country to get the relevant data to my car and I don’t particularly want to go through 2000 pages of stuff I’m not sure I’m looking at….

Sorry, you want others to do the work for you?

I’m just asking more experienced people if they know what the wires are for under my car seats…

It very much depends on your cars setup but from what I have read its Airbag, Heated Seats, Seat occupancy sensor and cant recall what its called but the sensor that comes from the seatbelt buckle.

I can only confirm on my 2014 car the yellow one is the airbag in the seat.
