Thanks Raven.

I've looked at similar diagrams, but not one exactly like this.

Couple interesting things here. In this diagram, it appears that the pedal does have the 6 pin connection I need, although the actual connector could be different.

Also, I assumed the path was from Pedal, to TAC Module, which communicated to the PCM and the Throttle Body.
In this diagram, there is no TAC module (or it has been named the Powertrain Control Module, which I think of as PCM, the main computer.)

Is it possible that this diagram (and potential the pedal I purchased) is for a V6 model, and the V8 is different and uses a separate TAC module?
