I am building a rack set up with 4 slots each holding a 27Q or 28Q sterilite container for leopard geckos. I have reostats already and am using 1-3"-1ft long piece for each slot. I do want them ran to one single plug then into that dimmer. All of the websites that post wiring diagrams wont come up on my computer for some reason! They will be set up for belly heat with all wires going out the back. Just need to know how the negative/positives connect? Does it go each positive together to one and each negative together to one? This is a stupid ? but i want to make sure nothing goes wrong!
