S4 car
S5 alternator

 

okay Y/W its the one for the temp sensor,now i just need to find out the one for the alternator(dummie light)

 

well acording to the wiring schematics B/W wire its the one for the alternator idiot light,let see what happens

 

there is a white plug on the pass side ,, its up by the heater box and fire wall ... thats were the y/w wire will go after u clip it on to the stock temp sencer.... and i think on the white plug it will have the y/w wire

 

thanks buddy that is where i hook them up.
