Question on Gauge display for On Board Computer

[PaulE]

My car is a 2003 and didn't come from the factory with the on board computer. Quite a while ago, I added the 4th stalk, bought the well-made harness from PDwight and had my shop activate the OBC. My OBC stalk scrolls through all of the available functions, and I can set and cancel the speed alarm with it and reset average mpg and the trip odometer with it. But all of the OBD functions appear on the trip odometer line in the screen. In the owners's manual, there is a section on gauges for cars without the OBC and another section for cars factory equipped with the OBC. The section for cars with the OBC shows the OBC functions on a third line, below the trip odometer. The owner's manual also shows pictures for bringing up a function on the left side of the screen to scroll through the various OBC functions and oil level. I can't do that on my car. I double checked that I inserted the 4 wires into the correct slots and that they are securely installed. A couple of pictures from the owner's manual showing what I'm referring to are below.

I'm wondering if there is another step to activating the OBC with a Durametric or PST, or if the cars that were factory equipped with the OBC have a different gauge set. If there is a trick to bringing these screens up on my car with the gauges I have, I'd like to do it. I've done a search and haven't come up with an answer. Does anyone know the answer?
