This is the cable that runs from the second heater lever from the top, down to the heater control valve (down by the spare tire).

The original cable had one blue and one yellow paint mark. This one is made in the U.S. and is sufficiently sturdy. 920mm from the slight bend in the metal cable on one side to the other.
