Celica Forums General Discussion General Air/fuel gauge and water temp

Aight i got some new gauges and i have no idea how to install them. Does anyone know what wire hooks up to the O2 sensor. I have no idea which one to hook up 2. It says it hooks up to the O2 sensor? and then the water temp? where does that hook to? im totally lost any know? Pics would b very helpful thanx. Oh and if anyone knows how to install them in the air vents? can they even be removed?

the vents can be removed but you may need an adapter in order to make them sit flush in there - depending on your gauge sizes...

there is an install guide for the A/F gauge and pics for hte wire its on the passanger side by the dash mat.
