Can you guys please look over my LED-WIZ wiring diagram?

Thanks guys. yotsuya your avatar reminds me of pee-wee haha. I did run a few tests last night as you mentioned and they work great! Very excited to get the all of them in my cab. I'm just trying to understand where the current is going when you plug a line into the Voltage Bank Select. I know I don't need that for this install in-particular but if I ever need to use two voltages I'm trying to understand if plugging a different voltage into one of the bank terminals notifies LED-WIZ what voltage to allow through either pins 1-8, 9-16, etc. or if it is actually passing current through the voltage bank terminal and to one of the 4 main pin groups like 1-8. In other words, why do I have to notify LED-WIZ if I'm going to properly group the component on 1-32 (in groups of 8 ) anyway. So far all the posts seem to just tell you how to do it instead of why you have to first connect the voltage to the Voltage Bank Select. Thanks!
Nephasth, honestly thanks again. I've read through the instructions twice more as you suggested on the bank wiring configuration and it's still vague. I've carefully read the instructions probably close to 30 times now. As I'm sure you are well aware of, even the instruction section describing the banks also state to ask for help, "Note: If this section is not understood by the user, it is highly recommended that an email be sent to [groovygamegear.com support email] for clarification." Again, I assumed it would be good to have the knowledge added to this site instead of filling up Randy's inbox. If there is a thread on this site that describes how/where the current flows from the Bank Selection in more detail can you please link me to it and I will read it thoroughly. Again, I'm wanting to educate myself on how the current is being handled at the bank. I'm confident I understand everything else and can hook my setup with zero problems as I've verified it by reading multiple threads on this board. I'm just wanting to know so that I have a better understanding of the device. In my eyes this isn't an issue of reading comprehension but my inability to find the forum posts I'm searching for to verify what I assume. This is because I'm semi new to this hobby but I have been active in it for a few months now. I don't need my hand held just a finger pointed in the direction I should be looking. Thanks!
Thanks all!

i think what u miss in the doc's
is they are grouped
so lets say 1-8 u run at 5volt and 9-16 u run on 12 volts
2 seperate feed's
+5 +12 so what ever u put on the :feed line: must be the matching voltage for the :load: the same,so on 1-8 u have a switched +5 on 9-16 u have a switched +12
so u would expect to put a 5v load on 1-8 and 12v load on 9-16
that is the basic skinny of it

To keep it simple, I usually recommend that where higher current loads are concerned (such as would be the case when doubling up Helio9 units on the outputs) the +5v be attached to the Bank Voltage Select terminals for the banks to which they are attached, as they are 5v units. Is it absolutely necessary? Probably not, but for the 5 extra minutes it takes to do, it won't hurt anything and could offer some extra protection for the driver. Just don't use devices which are over +5v on those banks of outputs after doing so.
It really is simple to wire these, but there are different ways they can be used. Sometimes the simplicity gets lost in the extra info and warnings, but we have to supply them.

Thanks guys, that helps a bit. I went ahead and worked up a drawing that asks my exact question. I hope this helps both you and me haha. Thanks for staying with me through any of my faulty communication!
RandyT:
The first one allows for stored current, as a result of a collapsing electrical field, to find a safe path to ground through a built-in diode, rather than backfeeding into the driver and damaging it. It's usually only a concern for inductive loads, like coils and relays, but can also occur with larger currents over long distances of wire.
The second one should work fine with just LED's over reasonable wire lengths.
The exact path doesn't matter. You can get the +5v line there any way you wish.
