yeah man, what he said.. wires to wire for mechanical air fuel gauge?
check the diag block. there's an o2 test connector in there. connect it to that wire and you are good to go.

I don't know what you mean by "mechanical" gage but if it has a D'arsonval movment don't use it. You need to be real careful what you hook up to the lambda signal because it can be easily effected. Whatever you connect to it must have a hihg impedance and mechanical gages don't. In fact I know of at least two electronic A/F gages on that market that'll attenuate the O2 sensor signal.

If its a narrowband just connect the sensor wire to the blue wire on the 02
