    Since my 76 was taken out of the garage to the shop, I was using this time to add some shelves, reorganize a little and move things into the attic and so on.. once the car moves back in, I wont have much access to that side of the garage, so I wanted to go ahead and install additional lighting in the garage.

    In the above pic the green are existing light and wall switch, the 2 black are where im going to place the new shop lights.. I already have everything from previous DIY projects, so its just a matter of the wiring.

    I want to run the 2 additional lights off the same switch, these are florescent shop lights and just want to tie in with the existing one so I can turn them on together.

    Can anyone offer how to on the wiring? I would think that they would need to be in series? is that correct?

    There is a standard based on box volume for how many wires can terminate in it. I don't know the code, but a standard single gang box probably should not have 3 sets of wires into it, plus the feed (parallel setup), even though there are generally at least 4 openings for wires in the box.
    Series wiring avoids this by adding the new wires to the existing light (assuming there is a box at the light) or 2 sets if you run to each of the new lights from there.
    There are deep boxes available, or you can use a bigger 4x4 switch box with a single switch cover and run them all to the switch. Then you would also have the option to change how they are switched in the future.

    Sorry, not really a concrete answer. One of the real electricians may have something to add.

    You wouldnt need a box at the light, would you? Can't you wire off the existing ballasts? Also, most ballasts come with wiring diagrams, and there are different kinds.

    that's cool, I just want to make sure when I start that I have anything I may need so I don't have to run to the store..

    Well go up in the attic cut and mounted the electrical boxes and actually found 2 wires already coming out of the exiting light I was going to tap into that are wired and live, so just dropped them into the new boxes and ready for the fixtures to be installed.
