CT3925 Fuse Block Assy. One of three blocks that hold your fuses located in the engine bay. You're not really using American fuses are you? Comes complete with center holes to equip you with spares. That Lucas, so thoughtful! Take note, these come with the Fuse Box Covers (our part number N15/19).  But, don't forget to order a set our lovely Fuse ID Plates (pat number  N15/21/A), to complete the look!
