I was looking for a pinout for my 705TSV so I could do some surgery on my cable to make it shorter. It has a 26-pin mini-D ribbon connector (not 20-pin like the others I found posted here). I haven't seen this posted yet so here is the drawing from Xenarc of what the pins correspond to for the 26-pin version of their cable harness. (Image quality scaled down to be hosted here)
