So i found out that the purple/white wire is the signal wire for my rear O2 sensor. I want to hook up my wideband through this so that i can log actual AFR and use the AFR% error histograms.
I have a AEM wideband and i was wondering do i just need to cut the purple/white signal wire from the rear O2 sensor and hook it up to the 0-5V output on my wideband?? I realize that i will have to do come custom PID work but i think i got all that figured out. Do i leave the other wiers from the second O2 sensor hooked up as they were?? Or should i disconnect all of the wiers and just hook up the signal one??
