I believe those cable connectors are just electrical splices which VW 
repurposed for their heater cables. I've never seen one that needed to be 
replaced, but I must have a few from parted out older cars. They are plastic 
on the outside, but metal within. They should last forever unless they are 
abused.

The little folded-over section at the end of the wires is not important, and 
actually makes installation a bit more difficult. I cut mine off so I could slip a 
length of Teflon tubing over that part of the wire that slides inside the metal 
tube. That made those slide much easier. Being down on the floor makes 
them prone to rust and sticking.

I would adjust the cables so that everything is off when the lever is fully 
forward. No other adjustment should be necessary, and the lever will stop 
short of it's upward limit when the cables run out of travel. If you find that 
"fully ON" does not open both cables equally, you could experiment with 
moving the lever ends of one of the cables to a different hole in the lever.
