Hi, folks Just wondering if there are any electrical gurus out there who understand the symbology in the WSM wiring for the "System Protection Fuse Holder Module" (found in the passenger footwell area). Namely, the box symbols and "T" shaped symbols. Image Unavailable, Please Login None of the symbols seem to represent fuses. There are numbers in the diagram (1~16), and they seem to be attached to the box symbols but there is an extra row of boxes labelled (A, B, C, & D) attached to nothing (20 boxes in total). All the T-shaped symbols are attached to the external wiring, so they may be fuse terminals, but there are boxes also attached to the external wiring (top row). The boxes are joined by lines, so may be part of a bus bar system. If a "box" and a "T" represent a fuse, then why is there an extra line of boxes? I'm currently trying to create a wiring diagram for the doors and windows. There are 8 wires going from the window/door system to the system protection fuse holder. The diagrams link all of these wires to either a box or a "T" symbol, but it doesn't tell me which fuse they are attached to. Thanks Cheers Ian.
