Lens B to correct lens A.

Not, the reason for this post........
For others...
The driver board the wiring, I had forgotten.

Look at the original post, page 1 #1.
The pic of the unit.
2 wires one a vid out , another the power supply.
They just have 2 tap outs, of grnd on the driver board.
1 for power supply
1 for vid
