How to /setblock a specific type of redstone (Debug mode)

Solution 1:

@ModDL gave a great answer, but sadly on my Minecraft 1.8, when I tried that using blockdata, it didn't do anything. I still appreciate his answer, although.

Check out the answers at How to place redstone using Command Blocks.

Even when I first examined it using F3 on my Minecraft in 1.8, it showed it like this:

north:none
south:none
etc.

I tried modification using /blockdata but that didn't work.

So then I thought: Hmm... what about data values?

So then I tried /setblock (x) (y) (z) redstone_wire (0-15) and then like a miracle, it worked!

It turns out Minecraft is showing what the damage value corresponds to.

In 1.8+ it interprets the damage value so that it's human-readable.

But in 1.7 and lower, it just shows (block name)/(damage value).
