Pull my wife's seat (heated, zsp) and plug it in my car. Does it have heat? If yes, than I know this is a non heated seat.
If no, then I know the wiring is off. So, I will pull out the multimeter and check which wire gives power when the heat button turns on. I will then try and find the corresponding wire on the seat. If no wire, then I assume no heat. I will then retrofit (or at least try very hard) my old elements into the new seat. If there is a corresponding wire then I will assume heat and then I will solder in the old harness.
At this point I am pretty sure this will be a retrofit job, though.
I will take pics for anyone else who wants to see how this goes...
Cheers and happy holidays!
Yes, please take pics and some notes! That would be helpful for all!
I may to pull apart my seats to see if they have the grids also.
In my (limited) homework, I cannot find different part numbers for the seat covers or cushions (at least on U.S. cars...not true for ECE cars) that have/don't have heater elements. This leads me to believe they may be built in - of course, I may be wrong, but that's how I see the parts catalog.
