My new Mustang has spoiled me with its heated seats but unfortunately I can’t drive it in the snow.  I found this universal seat heater at work and decided to give it a try.  It was pretty easy to install as the factory covers kind of snap on.  I didn’t even remove the top cover, just opened the bottom and had enough room to slide it up inside.  There was plenty of space on the switch panel for the new switch as well.  It works great, I put it on high and it heats up quickly.  I usually drop it down to low after a bit though.   It costs about $70 and took less than an hour to install. 

Nice, just what I need for those cold SoCal mornings.   A clean switch install.  I see it uses a relay, where did you get the power from for terminal 87 and 30, switching power and main power, of the relay? 

It’s a two wire hook up, grounded it on the floor by the seat and ran the power wire to my extra fuse block under the hood.  I wanted to hook it to a switched power source so I could leave it on and it would warm up when I used my remote start.  I need to clean up my under dash wiring though, got some fuse taps and such and don’t even remember what they are for.   It’s on my expanding list of things to do to my truck next year.
