Hello, I've not been on this board in quite some time but I just looked in and saw this post.
The TOD has a separate controller that is located under the passenger seat and works independently of the ECM. The type of ECM or what ever you would like to call it is in the center console, has red, white, and blue connectors, and is labeled 3.5 MAN. I don't have the part number but you can use the one from the Trooper unless it is new enough to have the ECM in the engine compartment. Hopefully this helps and good luck.
