b16a distributor.....how do these plugs wire up???

My original has only 5 wires and has a square plug end. My b16a distributor has 7 wires and has a different plug. How do I need to wire this up?

what kind of engine are you wiring this up to? seems to me that if you were using stuff made for your motor, it would have adapters that were compatible.
