2 tier viv electrical setups

[cc1025]

I'm in the process of building stackable 4x2x2 vivs for my 2 beardies, and I was wondering how everyone hooked their lheat emitters, basking lights, and uvb bulbs up. Should I use 2 zilla 7 day timers, one for each vivarium? I am building a stand for them to sit on so I will have some space underneath the vivariums to put all the electrical. Post some pics of your electrical setups if it will help me get some ideas.
