okay, i looked into how you can add heated seats to your challenger. a friend gave me his center dash bezel with the seat heater switches. he changed to the carbon fiber one and gave me the silver bezel. (thanks Pat)
after snooping around under the dash, i found the connectors for the left and right heater switches. i routed them to the center dash area and plugged them into the switches. i then enabled the front heated seats in the TIPM.
the switches are now powered and light up when the headlamps are on. since i don't have the heater pads under the leather, the switches don't do anything more than light up.
i have another car, an '06 magnum sxt with non heated leather interior. i have spare heated leather seats and the switches for that car. i will install it, program it and see if it works. then we will know if the dealer can add factory heated leather interior.
