trying to wire my wideband to my ECU directly aswell add Bluetooth datalog. I got a chipped p75 already my question is my wideband gauge there’s a right connector going through the firewall directly onto my o2sensor like 6 colored wires and my left connector black grounded and red wired to fuse with a blue and white wire not used. Which connector do I wire up to my ECU. it’s D14 and A25 and A26?



i would think it be red black on a25-a26 and white on d14 I think for the left connector someone verify before I screw smth up

 

A23/A25 for ground/power, respectively. Your choice of D10/D12/D14 or B6 for input. B6 and D12 (my preference) are totally free. D10 is full scale if you want to disable your ELD for whatever reason. D14 requires modification to read full scale but there's no use for a narrowband if you are going to run a wideband with a modified ecu from here on out.
