Hey i got a question about GEM modules, what is the difference between a Version G module out of fuse box with the part number F81B-14A067-AE and A version B module out of a fuse box with the part number F81B-14A067-AF. Also whats the difference between these two fuse boxes. The reason i need all of this is because my door buzzer wont go off until the key is off in my 1999 f250 also the cargo lights and dome light s do not shut off and i have no spedo.
