Seat heater wiring diagram

O.K. Some people have asked me for the wiring diagram for the oem TL seat heater switches to aftermarket heaters. This is how I did it, it works great, it may be overkill to some. Forgive the crudeness of the diagram.

Thank you very much for posting the diagram.

Are you using any of the relays supplied with the seat heater or just bypassing their entire setup/wire harness and connecting direct to the pad via the SPST relays?

The ones I got did not come any external relays.
