through 20A fuse (No. 31, located in the fuse and fusible link box)

to rear view camera control unit terminal 1.
When ignition switch is in ACC or ON position, power is supplied

through 10A fuse [No. 4, located in the fuse block (J/B)]

to rear view camera control unit terminal 2.
Ground is supplied

to rear view camera control unit terminal 3 and

to rear view camera terminal 2
