How do you tell where pixel one is on my mega tree. I have set up my 2016 pixel mega tree. Up down up down and counterclockwise. 42 pixels per string with 48 strings. When I physically go to wire up my tree in the yard. Where does my first strand start. I'm thinking if looking at my yard it would be on the left hand side at the base. Or is it on the rear in the centre. How do I tell.
