Going to be sorting out the wiring on my escort zetec turbo over the next few weeks. Had a quick look earlier and found a lambda sensor that goes back to the ecu.. Is this needed ? It's just i've already got a wideband lambda sensor in the exhaust that goes to my afr guage, just wanted to know if I need to get another lambda boss welded into the exhaust or not ?
