I have just recently put an air/fuel gauge in my Lancer ralliart. Its a digital one i am not sure is they make a mechanical one but anyway does anyone know what color lead i need to attach it to. I know it has to be the high Volt wire. I also know that this o2 sencer is heated to its 4 wires. Theres black ground and i think the white wire is postive but theres an blue and one other i am not sure which wire it is does anyone know? Or point me in the right direction

Usually in automobile wiring. Black is ground and Red is hot. White, blue, green etc are usually acc wires. Sorry i've never hooked up a narrowband mines a wideband and it had 4 leads red ( hot ) black ( ground ) were the only ones I needed for it to function the other two wires were optional acc wires for AEM EMS.

Here hope this helps. What kind of gauge do you have so we can figure out what the white wire is.

How I would hook it up is just run your red wire to a 10 amp fuse in your in dash fuse box its easily removed and you don't have to hack into your stock wiring harness make sure you use it on a fuse thats connected to the ACC line that way it doesn't stay on and you kill your battery ( Gauges fuse is a good one ) wrap the wire around a tip of it and plug it in then ground the black wire to a bolt on the chassis ( it helps if you have a connecter instead of just doing the bare wire ) then the signal wire ( in this picture is violet but yours is blue ) should be wired into the blue wire coming off your o2 sensor you have a black covering on your o2 sensor and you should be able to slide it back and just splice it in. I'm going to guess that the white wire is your 0-5 volt and should be wired into the white wire coming off the o2 sensor BUT don't hold me to that double check on that one.
