ok, i put a nwe 02 sensor in, and i hooked up my o2. i ran a power and a ground near the gauge, but i can't get the gauge to read anything. i tried hooking it up to every one of the 3 wires coming off the 02. am i doing something wrong? black is ground, red is power, and green is signal. i tried green to every one of the three. it's hooked up now but it just reads lean. when i rev it the light gets a little tiny bit brighter, but thats it. . ..any ideas?

 

but I know in my friends del sol his has to warm up a little bit before it will read, mine is powered but just stays on green, this is a good question because I was gonna do mine soon. do you have the led one like mine or the more acurate kind?
