M- = Ground to fan motor
M+ = Power to fan motor
30 = Battery power (fused)
31 = Ground
Pin 6 = PWM input (in your case - E40 controller - J1-36)
Connector is sold as part of fan harness, which is part of cooling fan assembly - Part # 15819952 (AC Delco 15-80657). I found a few connectors separate years ago, but have since used them all.
