I would think 3 pairs would suffice for any flavor of resolver. The only thing I can think of that needs 5 pairs would be if they had two resolvers in there (coarse and fine). You'd have one exciter, and two sets of sin/cos outputs. A differential-output encoder with index would normally have FOUR pairs, power, A B and Z. Possibly a 5th pair could be an encoder valid signal.
If all the pairs of wires have relatively low resistance (a few hundred Ohms, max) across that pair, then it is almost certain it is a resolver.
