Eric,
I had to lookup NOS and found it means New Old Stock. Hmm, maybe it should have been ONS Old New Stock. Nevertheless, it is old and hasn't been used. And it was free!
Your ICM definitely looks like it needs to be replaced. Leaking and it looks like it may be the original.
I like the concept of the one you found that works with both 4 and 5 pin plugs without any mods. Sounds great, but I am not sure how they do that. It is supposed to require some rewiring to switch, so how can that be done inside the ICM? Hmm. Maybe try searching for it in some Mopar forums.
I guess Griff fell in the black hole of his new game...
