What are the available options? Can you take a pic of the back of the rec ? Star Trak is an old one, I never had one but somebody here should be able to help you figure it out. Usually there's 2 bigger wires for the motor power, and 3-5smaller ones avail to read the sensor feedback. Most receivers I have ever used would work just fine with 3 wires for sensor, usually red, grn,black, or red,grn,brn. Red for DC, brown for feedback pulses, +a ground wire.
