If you have high impedence injectors, you can ditch the resistor pack and don't have to worry about the flyback circuit. Your MS should have a tach/RPM input wire that connects to the crank sensor output. The speed sensor output wire needs to go to the stock speedometer. You will certainly find the stock speedometer trigger wire (yellow/white stripe) up near the speedometer. If you left your stock harnesses in place, you will also find this wire near the stock ECU location. The ignition switch ON wire (heavy black/white stripe) is up near the ingition switch. If you kept your stock harnesses, you will also find it near the stock ECU location. The MS fuel pump wire controls the ground path to the coil of your chosen fuel pump relay. It doesn't care if you connect it to the stock fuel pump relay or run it back to an aftermarket relay for the "fuel pump rewire mod". If your MS has a tach output to drive a stock/aftermarket tachometer, then you can connect the MS tach output wire to the solid white wire up near the stock tachometer. If you kept your stock harnesses, this wire could also be found near the stock ECU location. A universal standalone ECU installation is pretty deep stuff. You really need to have a factory electrical manual handy. It will have diagrams of every wire, circuit, and connector in the car. Reading through that will not only help you find the right wires, but gives you an idea how any ECU (stock or MS) interacts with its sensors and actuators.
