Yes, just ignore the ground pin on the resolver side. I dont' think it's necessary. It was in case there was noise, but the lines are so low impedance (like 16 Ohms DC resistance) that I don't think it's worth using a shielded cable, and grounding the drain wire. At least I've never had any trouble getting it to work. Also, ignore the DOS/DIR/LOT pins. Just use a 5 pin connector for +5v, ground, A,B,INDEX.
