heated seats in a charger/300/magnum

Has anyone hooked up the heated seats in a 2006 Charger, 300, or Magnum to an aux output on a remote start/alarm brain?  Is there a wire at the switch that just requires a negative pulse? Or am I getting into resistors and relays for this one.  I'm also interested in the rear defroster for the same reason.  Thanks for any help anyone can give me. 

Driver Heated Seat Lt.GREEN/ Lt.Blue At The Heated Seat Switch Negative Passenger Heated Seat Lt.GREEN/ Gray At The Heated Seat Switch Negative Need a 0.7 second pulse to turn it ON in Hight level, pulse it again it will go to medium, another pulse will turn it OFF Should not need a relay but if hooking both up to same out put diode isolate them so you don't turn both on when you push one button

Thanks a bunch for this information.  Invaluable!!
