Air/Fuel gauge
 

i have a window column gauge set(volts and air/fuel). i got my volts all set up and running and i have a ground for my air/fuel but how do i finish it? is it something i need a professional to do?

what do you mean?

do you havepower for the guage?
does it have ITS OWN ground?
did you tape the hot wire that comes from the o2 sensor?

also is this a narrow band a/f guage or wide band?

it has its own ground, but now that im thinking about it im just going to have someone do it for me. my car club's president owns a garage that does that kind of work so he's going to hook me up for cheap.

Its simple wire your red to ign and black to ground, you could just tap it to volt gauage and the last wire could be blue,yellow or orange gets splices to one of the oxyen sensor wires.
