OK, some updates,
I found the pigtail, napa online or at the store, part number EC#101, or ECHEC101, $9.49.


Only come with 3 wires, but you only need to hookup the big one and one other, not sure which one, but I'll find out later.

As soon as I get some time, I'll swap out the old alte and go for it, maybe later this week...
