I have question for anyone who can answer, i have a Faze A/F gauge that i bought off my friend, it came wit a black and red wire. He said when he had it on his Honda thats all he used and it worked. Does anyone know if there is another wire that is supposed to be on there or is there a way i can still make it work on my car?

 

theres supossed to be a purple wire for the sensor...tell your friend hes an idiot. red wire is power black is gnd.

 

aight, thank you. i figured something wasnt right. i just wanted to get a 2nd opinion
