I don't have any answers for you - just an observation. In finding the leak in the wacher system on my '90 124, I found that the hose/wire had been routed such that a large hole was abraided through the tube and the center wire. I thought, "no problem" I'll just splice it, with a short section of aluminum od copper tubing and solder the wores together. I found that the center wire is one of those extremely fine threads of wire wrapped around something similar to fiberglass, not your usual wire. Then it occured to me that the whole length of tubing had to be heated, not just the nozzles! I ended up splicing the tubing, and doing without heated nozzles/tubing.
I did see what appeared to be a temperature sensor at the end of the tube just where it attaches to the washer fluid tank.
