I would think so. Two of the pins are +12 and ground (unless the motor uses a 5VDC regulator prior to the connector), and I imagine that the other two are the high and low speed. Try dropping Terry a note and ask if he's used these. BTW, what's the part number and mfg? The top pic is a bit fuzzy.
Maybe we're more than what we think we are...
...or maybe not.
