MKS Gen L and BL Touch Issues

I have a newer generation Tevo Tornado with an MKS Gen L controller that I am currently trying to install a BL Touch v.3.1.
I just flashed Marlin 1.8.10 modified for BL Touch. The probe comes to life just fine, but trying to auto home for the first time, the hotend gantry moves downward in the Z-axis with the probe extended as it should, but I will manually trigger the probe and nothing happens. The carriage keeps on moving towards the print bed and so I have to kill the power before it damages the printbed.
During the wiring part of the install, I did have to swap the black and white pins because the hotend was moving in the wrong direction(Z+).
Any Ideas? Better yet, is there Marlin firmware for Tevo tornado that supports an Infrared differential sensor?.

"I did have to swap the black and white pins"

The black cable should be in the center and the white cable down the bottom. Is this how you have it?
