wiring plx300 wideband to ecu
hi i did a b-swap into my 92 4 door civic and bought the plx300 wideband a/f monitor... i just wanted to know if anyone could tell me where to wire the gray and white wires to the ecm so i can replace my stock o2 sensor.. or send me a link to the entire procedure...the instructions included were 1 paper and they suck... thanks

If your running closed loop, (still maintaining the stock O2 sensor), than your going to need to weld another o2 bunge on your downpipe. You cant use that one o2 sensor for both your stock ecu and you widband, it will not be accurate. The whit wire, i believe is for datalogging. Let that hang for a while but keep it accessible. The grey wire is for your autometer or regular a/f gauge. You need to weld another bunge for your wideband o2 sensor if your running closed loop. Just run open loop with a basemap and you should be set using only your wideband and a good street tune
