Anyone know which wires, or plug on the PLX box I need to run so that I can log AFR, and still have my gauge? I think I have the right HPT cable, just don't know about the PLX.

Thank's J

 

Looking at the green plug from the side you put the wires in, the first 4 from the left are inputs, 5 & 6 are grounds, 7 & 8 are outputs.
You need the plx analog wire to one of the inputs and a ground. I don't remember the specifics since it was years ago that I set it up but just looked at my cable real fast.
