Hi,
I upgraded my electric comforts to the electric sport seats from a 1985. I'd like to add the heated seat/back to them.
So I was wondering if the existing wiring harness in my 89 is the same for heated electric seats or do I need other wiring harnesses for it to work.
Thanks in advance

Re: Wiring (electric) seat harness on the 89
There are additional wires under the seat and they may be for the seat heaters. Best to look under your seat and see what's there then research wiring diagrams to see what they're for
I've never come across an e24 with seat heaters so I'm not well versed on the system

I was hoping someone here may have done this in the past.
I looked on realoem, couldn't find the wiring harness for just the electric seats so thinking maybe it might be the same harness used for heated as well.
If that's the case, I would need the switches, relays and seat and back heat elements.
I recall when upgrading the seats from comfort to sports, everything plugged in so I was able to used the controls.
I'll need need to look under the seat for sure to check.
Thanks and happy holidays
