Here we have a good used underhood fuse relay box removed from an 01-05 GMC 2500hd with the 6.6 Duramax. Guaranteed to be in good functioning order, but please review all of the photos as this is a used parts and sometimes clips can break etc, you will get the exact item pictured. This will ONLY fit 01-05.5 trucks with the LB7 and LLY engine and the matching part number. if you need any parts just inquire.
