Hey Neil
My Temp II sensor wires were all cracked and breaking, the connection from
wire to plug was poor, and the wires were just a little short causing them
to be kinda stressed. I went to a German Auto salvage and got another
couple of plugs for the sender...they seem common throughout the VW
line...Cut the wires with the plug on the end (at the junkyard) and then I
had room to make a good splice into my vehicle's wires...
No more problems with 'dicey' operation of my Temp II related
systems...Something about the wires on those plugs makes em get brittle and
crack the insulation...maybe the heat...seems fairly common that there are
connection issues at that sensor..Anyway, plugs like that are common
throughout the VW line.
