2nd O2 sensor on MAF converted f150
I have a 91 f150 with a 5.0 that I did a MAF Conversion with a mustang A9L PCM. The DYNO guy wasn't happy with me only having one O2 sensor. So per his instruction I have a Ford O2 sensor from Ford (80 effin dollar sensor) for my year truck and am a little hesitant to go off mix matched diagrams I've found online.
Any input, instruction, or info would be greatly appreciated.
P. S. All the info on what's done to the truck is on the forum "SD to MAF Conversion". I'll try to put a link in.

Why? Does the truck have dual exhaust? You did a DIY MAF conversion so what did you do with the single O2 sensor? Did you tie it to both A9L sensor inputs? That works just fine and is exactly what Ford did with the MAF conversion kits they produced for these trucks, but if you gotta have dual sensors then just install a second one in the drivers side header and wire it to the PCM, the input pins for the O2s are listed in the other thread you linked above.
