Many years ago (15?, 20?) I bought 4-pin male/female sets of plugs for my fluorescent lighting. I can individually remove the ballast, & 2 separate tubes (in separate light strips - aka plastic rain gutter). They've been working fine all this time. One end is square while the other is ^ -shaped. There's no way you can mix up the poles & contacts without really trying. The pin sets were bought at Radio Shack. Another nice system, so you did not need a lot of space to lift the glass aquarium tops (it helps in low clearance situations) was the sliding top used by O'Dell aquariums. It consisted of plastic strips mounted at the ends of the tank. In cross section it looked like an upside-down "F". The back glass sat in the slot formed by the 2 arms. The top glass slid along the rail formed by the short F arm (does that make sense?). This way the top (front) glass slid smoothly over the bottom (back) glass, giving about 6" of clearance in the front of a 12" deep (front to back) tank for feeding, cleaning, etc. without needing 6" of clearance needed for lids with hinges (that always split after a few years). O'Dell used to sell it in 8' strips so you could retrofit tanks. I still have an 8' strip, but could certainly use some more if anyone knows if it's still being made by someone. When it comes to timers, don't buy cheap ones. Buy heavy duty industrial timers that can handle the very high wattage that ballasts require only when they start up. In my experience typical home timers won't last long on multiple ballast systems. Of course the other option is to buy a standard timer for each ballasts used. Just don't overdo the wattage suggested on the timer or you will eventually fry its innards.
