A3 8V heated seat wiring


New Member
Hi guys,
I have bought S-Line, manual, heated seats from a 2015 A3.
I would like to install these seats in a Land Cruiser and use the heated feature.
Do you know if it is possible to wire the seats to my Toyota loom?
I have a factory plug (Toyota) available under the seats with a positive HIGH heat, positive LOW heat and ground. (See the switch below, it sends different voltages on the high or low setting)

Is it possible to wire the Toyota positive HIGH heat, positive LOW heat and ground to the Audi seats?

It is important to know that :
- I will not have the climate control unit (obviously)
- The wiring loom for the Audi heated seats has been removed.
- The Audi seats are manual so I don't need to power them up

Thank you for your help!

Hello again!
I have found out that I have the green plug under my Audi seat.
4 wires come out of that plug. Can I hard wire them to an after market switch/or to the Toyota low and high positive switch?
Can someone explain how to connect these 4 wires?
Thank you!

You would need to reference the Audi and Toyota Wiring diagrams in order to work out the function of each connection and then wire accordingly.
