I have a 1998 Ford F-150 XLT 4×2 that needs a new under dash fuse box. I’ve found several fuse boxes with the same part number (F85B-14A067-AA) but different letter codes. The letter code for my truck is ‘B’, indicating it’s for a 4×2 pickup. The boxes I’m finding have a letter code of ‘E’, which is for a 4×4 pickup. Do you think the boxes are interchangable, or is there enough of a difference that makes you can’t use a different letter coded box?
