I still don't have the battery blanket in, or the car warmer. But, I thought y'all would like to see how I've run the cord, so while it was nice out today, I grabbed some pictures.
In this picture, you can see where my block heater is, as mentioned in my first post. It's a little hard to see, but it's just about on the right hand edge of the picture, there.
Here you can see the cord coming up behind the AC compressor. It has always come up there. It used to go from there up to the rad support and then out. Now, as you can see, it routes back to the fire wall.
On the fire wall, as you can see, I found a "tunnel". That has a hose of some description running through it, and had enough room for me to feed the cord through.
Here's the other end of that, with my cord coming out.
The block heater cord runs over against the right fender, where it plugs into my extension cord. The battery blanket will also plug in here, when I get around to installing it.
Ford was kind enough to add clips to the fender bolts. I don't have all of the zip ties done up yet (I'm waiting until I have the battery blanket installed), but the plan is that the extension cord will run to the front along the fender here, using the clips to hold it in place. The battery blanket's cord will run to the back of the engine bay using these same clips.
The cord goes through a hold in the rad support (not pictured), and comes out under the grill, beside the right head light assembly, as shown here. I thought about moving it over under the light, but there's a gasket in my way, so it's fine where it is. Besides, here I can pull it back inside in the summer.
