I am looking to purchase the heating elements that go under the upholstery of e46 front sport seats. The car is factory wired and is already equipped with heated sport seats, however, I have obtained better condition otherwise identical e46 sport seats which do not have the heating elements in them. I would be a customer if you have an OEM seat heat retrofit kit or if you have new, uninstalled or used known-to-be-working elements from used seats. Thanks! Chris
