Sorry, not possible. The protocols are wildly different.
Well, it is possible, but not like he is wanting to do. You need some sort of converter and driver.
Since the OP was asking how to wire it directly, I answered it isn't possible, which it seems to me is correct.

If he'd asked it differently my answer might have been different too....

Right. Like I said... just not like he is wanting to do it. ;)
