Im pretty sure on this one but i can't find a solid answer. with the greddy turbo being internally wastegated i still hook the gauge vacuum hose to the intake manifold vacuum source right? can any-body lead me in the direction as to which wire is for the correct o2 sensor when installing an air/fuel ratio gauge? im about to purchase a helms manual i think,but can anybody help still until then?

thanks
