Add XYZ Touch To CNC PCB?

So I am helping out someone with an old CNC running MACH2. We want to add a XYZ Touch plate and I am not sure which port to attach it to.
Any thoughts? I currently have it connected to the AUXHome. Would you say this is correct?
Attached is a photo. It is all the same board but photo taken on the left side of the ribbon cable and then on the right side of the ribbon cable.

Secondly, any suggestion on setting up mach3 and configuring the correct pins? I cannot open the Mach2 config file for some reason to transfer those values to Mach3.
I have yet been able to figure out the proper pin configuration to put into Mach3 to run the machine. However it does run perfectly in Mach2.

Thanks,
