For the yellow (constant) wire, I used the fuse for the electric-operated
driver's seat (fuse #25). For the red (switched) wire, I used the fuse
for the cigarette lighter (fuse #34). The fuses are clearly marked on the
plastic fuse box cover by the driver's side door. Because of the extra
thickness of the blade, you have to apply some extra force to push the
fuses in. Bend the blades just enough to get the fuse box cover back on.
