I just use an indoor Grounded light timer. I have it go off 2 hours before I am going to leave the house for work, but I also run my extension chord under my garage door...that way I could use the indoor timer. Never had an issue. I do use an extension chord with a light in the plug that way I can tell if its on if I wake up earlier, and when I come out its nice to see that it has been on.
I use the timer from Lowe's like Zach mentioned. It's an indoor timer. But I also use an extension cord like Phil with the LED so I can look out to make sure it's on when I'm getting ready in the morning. The ideal time for plug in below 20° is 3 hours. Install a HPX and set the timer for 3 hours prior to leaving and you won't get the clatter and smoke.
Correct! 3 Hours is designated by Ford to warm enough at any temperature. I only start 2 Hours before, because it doesn't get that cold in the Desert, but cold enough that I like the starts better while plugged in!
