hey everyone, i got a free glowshift narrowband afr gauge (i know its crap because its not wideband BUT it was free) and i don't know what wires to splice into.

if anyone could help me figure out which wires i need to tap to that would be greatly appreciated!

i think there's two wires, one for the ignition and one for the o2 sensor, and i have a 2008 cobalt ls

also, i'm still waiting to recieve the gauge, so i'm guessing on the amount of wires there are(should be one for power because it has led's, one for the reading in the o2 sensor and the ground wire)

 

I'd just try to sell it on eBay or something rather than go through the hassle of install. It's not going to provide any useful data to you really

 

Well i kinda wanna use it until i decide to invest in a wideband afr so it would be great if anyone could still help me figure out the install to this one

 

So, i think i found out which o2 sensor wire... is the signal wire the purple/white on my car? And can i connect the positive/ground to the headlight wires?
