I have a 2007 Dodge MegaCab 3500 SLT. It has manual seats, i have found a set of power leather seats for it. does anyone know what this mod intails. There is a plug under my seat that has many wires on it, it is plugged in the existing seats for the seatbelt warning system. is this just a plug and go deal. Also if anyone has any info on hooking the heaters up. is this plug and go?
