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
