mine friend have 96 Thunderbird V8 4.6L , thats same engine like you guys have in -96-98 Mustangs
I already installed A/F ratio gauge in mine Mustang but I have 94 5.0 and thats little bit different than 4.6 in wiring and you guys have 2 more O2 sensors
So question is which one wire on left front and right front O2 sensor is SIGNAL (or where I have to connect signal wire from gauge)
Thank you

I'm sorry for my writing , I'm from Europe, Bosnia and my english is bad , so don't criticize me
