Ok , so I bought this control box

and have it soldered together. I have a 3 wire O2 sensor on my manifold and I know that I splice one of the pots into the wire that sends the voltage back to the ECU... in series right?

What I'm not really sure about is where to splice into the MAP sensor at. And I'm still not sure what it's going to do to manipulate the MAP voltage.
