If you remove the cover over the lighter socket, you will see two
screws. When you remove them you can move the entire panel aside and
gain access to the central electrical unit. The bulb integrity relay may
be black instead of red but it is the only circular relay in the rack.
The brake light terminals are marked 54R, 54L and the high light is a
black wire with a yellow trace.
The goal when driving is to miss the maximum number of objects.
