I am working on a small project to use an application that generates a square wave frequency and using the soundcard headphone jack to take that frequency and feed it into my oscilloscope.
I am able to adjust frequencies in my application, but the problem is my V p-p is 500mV. I need a voltage of about 5V (I think). I am trying to simulate an RPM frequency for a car and I will be feeding my car's ECU this stimulated RPM. From what I have gathered from a friend, using a audio output transformer from Radio Shack would allow me to achieve this.

On one side of the coil I have blue, black and green wires. On the other side there is red and white. Assuming this is the correct components, how would I go about wiring this?
