This is for a four lamp cct. It shows the yellow lead as being a return for the lamp and not a ground wire.

The green (ground) lead on the power cord should be attached to the ballast case. The black/white leads are the hot/neutral leads - just match them to the ballast leads.

What I have done on my connection board is to place some half inch bushings (a stack of washers will do) between the wood and the ballast - it helps to dissipate the heat. Plus you don't have something that generates heat right next to a combustable material.
