Sorry for the brief hijack, but will someone clarify something for me; are you saying there are normal 6.9 controllers that screw in the head and use the existing harness, that are no longer prone to failing and taking out the glow plugs? If so, which controller would I need? That would be a simple and relatively inexpensive upgrade.
Yes,
Here is a link to the thread that Mel made about the controller:

It came from Accurate Diesel according to the article.
