Seat heat in a Custom

[Cccchris13]

Anyone had luck installing OEM seat heaters with OEM switches into a Custom? I want to keep the 40-20-40 bench, but my back could always use a little heat, and the bum as well in the winter. Thanks!

As I stated in my other post I drive a 21 TB Custom, and am just wanting to finesse it into something a bit nicer!
