Note that these are on the other side of the ESD circuit, and after the isolator. If you have any kind of static on the line it's going to transfer directly into the controlling chip. It may be best to attempt to emulate the ESD circuit (or at least put an isolation circuit in place) to prevent that.

I also noted that the schematic is showing the ID line is connected, something the h.e.n. crew said was not the case last I recall? Or maybe it's connected in a way that we can't read it? Hmmm... In any case, the one toward the battery should be D+.
