my guess is that if it's a "limited", it is probably pre-wired for it. if not, there are a/m options you can buy as well. my wifes focus zts(top of line model) did not come with the heated seats, but upon inspection under the rug, the wires were there, so all i had to do was buy the required parts, and it has been working fine for over 4 years. pull the headliner down and do a visual.
