i tried installing my autometer air/fuel gauge today and it turns on but doesnt work. i wired the black wire to ground, red to a fuse, and purple wire to the o2 sensor signal wire (white according to haynes manual). the gauge turns on but just has a green light on rich, even at idle it stays at rich and doesnt move. am i suppose to wire the purple to a different wire?? i have a 95 civic ex.
