I have a couple of questions regarding the diagram.
Does U-shape drawing on the lamp mean I should use a jumper wire or why do 4-5, 6-7, etc. cross-over at the bulb they way it's shown?
And for connection 2, see how it goes off to the left and form a dot - does that just mean I should splice it with wire # 1?
Last question, while the dimmable interface has a grounding wire slot that requires a grounding wire from the ballast - the ballast itself has no slot for a ground wire connection. Should I just leave it empty?
