I just got a new to me 05 6.0. Its had a decent amount of work done to it, most of which I can ID. The ficm however, I cant figure out. Its definitely not OEM. the case looks light green, and the little plate on the front has a star engraved on it. I havent had time to pull it to see if there is any other markings. Any ideas? Any way to test to see what voltage it is set up for? thanks!
