Heaters are very simple, just stick them under the insert area of the seat cover, and run the wire out the back. There must be some adhesive strips either built in to the heater pad, or separate. If you can cut the hole through for the listing, I would do that first and then hook it up to power to make sure it works before closing it up inside the seat. I think there must be only certain areas you can cut, so make sure you read the directions very carefully. Good luck.
No one lives forever, the trick is creating something that will.
