If you are in function table 1, Apply 12v power to the red/white wire.
If you are unsure of what function table you are under, preform the following to factor reset... When you hold the White wire to ground, you are looking for the 3rd Steady high (~6.5seconds in) and then release from ground.
Shoot me a message if you are still having a problem.
When the light is flashing, momentarily touch the white wire to ground for >6s and <7s (light will go steady high, steady low, off, steady high, steady low, off, steady high) then release.
