Hi.
Anyone know what this orange wire is for?

I've been going through, cleaning up this 2007 GT 4.6L
Rodents lived in it.
They did a number on a few wires, but I'm making great progress.

Today, I found this orange wire cut in half.
- I fixed it, but don't know what it's for.

I've searched the forum threads and internet... no luck finding anything similar.
Anyone know?
Thanks for any assist!

I found a thread where someone was looking for a block heater. It's the same connector / same plug. Sure enough, I looked around and found the plug zip-tied up in front.

 

Yeah, I was gonna say, when it's plugged into a freeze plug like that and it's in cold weather conditions, block heater.

Thanks for confirming,
