Does anybody know where I can find "F22/1 Auxiliary Fuse Holder (trailer hitch/HS)" The HS is for Heated Seats. This 16A fuse feeds the Front Heated Seat Control Module in my '91 560SEL. I looked in the online Body & Electrical manuals but while it is shown on the wiring diagrams for the heated seats, there is no clue as to where it is physically located.
