Sorry for bringing up an old thread but I'm having issues with these exact seats. I purchased them to go in an 89 K5 Blazer. I have the power hooked up but haven't figured out the heat yet.
I have the seats only. Is there anything special about the switch for the seats? From the gauge of the wire used in the 16-pin connector I'm guessing the seats will get the power from a relay in the seat, and there is only the one power source.
Is it as simple as applying a 12v signal to one of the pins to trigger the seat heaters? Is there anything else I need to add?
Thanks for any help.
Here's the 16-pin connector:
