Current project is a Code 3 Arrowstik (or could be Narrowstik). It has a thicker black wire for a common ground. There are 6 positive wires for the heads as follows: 1-2-2-3-3-4-4-5-5-6. As you see, the ends are not paired like the inner heads are. It's much like the standard 8-head on the MX7000 is wired, but with an extra pair. If it helps to ID this model, the filter is one continuous 47" strip of amber that is flexible when removed. Both ends have arrows in black. The bulbs are incandescent 211-2. What I need to know is, what control box has enough leads to control the 6 circuits in this unit? The Code 3 boxes I have are negative switched and only run 5 circuits. I need a box to run 6 circuits. Positive Switched is preferred, but I can make a negative switched box work, as long as it can run six separate circuits. I do not want to just pair the middle pairs to make a common 5 circuit box work because that would result in four bulbs coming on at once and it would look so weird. If you can share a model number or pic of the box I need, please do.
