The square plug is for the lock up convertor and the other one is as you said for the speed sensor. If you dont hook these plugs the torque convertor wont lock and the ECU wont know when the vehicle is moving. The speed sensor plays a vital role in setting fuel trims and such peramaters in the ecu. You can buy a T piece that screws on to the trans, one output is for the speedo sensor and the other output is for a speedo cable.
