What's up everyone? I'm new at this whole things so don't get pissed. I got an air/fuel ratio meter and wanted to install it. It's used so it didn't come with any directions.... Is there anyone out there that might be able to tell me how and where to wire an air/fuel meter?

 

red - power
black - ground
purple - o2 signal

 

Ground should go directly to battery for best results

 

apparently your af meter is **** unless its wideband o2...

 

red =power
black=ground
purple=white wire on o2 sensor.
if obd2 on the primary o2 the one cloest to the engine.

 

what brand is it.if its autometer i would just go to there website and print the instructions.auctually even if its not there al the same.its simple.
