The replacement service part for the SA/SB fuse panel (located under the hood inside the engine bay) does not have the metal SA power distribution bar or "current rail". The under-hood fuse panel (SA/SB assembly) with part number 1K0 937 125 A or 000 937 125 is supplied without the power distribution bar. When the fuse panel is replaced with one of these parts, the power distribution bar from the original fuse panel must be re-installed on the new fuse panel.
