Im running four shielded wires to ecu. I cut into the wires just before the ecu connector and have white green, orange black, and white spliced ifrom the o2. When I got to yellow black I got to thinking.... I see that white green and yellow appear to join with other sensors. Did I just cut off the ground to other sensors? Would I cut off the power by wiring straight to the power pin for the oxygen sensor ?

I finally threw a code for o2 sensor...1. Tho there is continuity from the o2 connector to the ecu connector on all four wires I think something is bad. I get continuity through the c210 connector with three but strangely white green doesnt test good for continuity through it but still manages to reach the ecu connector.
