1999 Audi A$ Quattro Is it possible to run a 3 pin temp sensor to the 4 wires coming from the harness. ?
please be patient, this has become my problem passed on by p.o. temp gauge was not moving on first road trip, which led me to the present.
Other than switch radiators, and buy one that takes the 4 pin type, which is the obvious and more expensive choice... Is it possible to not use one of the 4 wires.?
I understand that they signal a hi and low fan speed, but I am not sure which does which. seems that the red with brown is high or constant power?
4 wires coming from harness:
1. red with brown tracer
2. brown solid
3. brown with green tracer
4. brown with yellow tracer
3 pin connector has 1. brown with black, 2. red with brown, 3. brown solid. what is the function of each wire color?
Bentley manual only gives color of 3 wires on the diagram and was not much help. Unless I am missing something.
please help
