The Toyota Prius has two 12 volt power
outlets, one inside the console and one in the dash. Both of these
outlets are inactive when the car is turned off and cannot be used
for a constant source of power. The following addition will cause
the front power outlet to remain on, even when the car is turned
off. This does not create any extra power drain or affect any of
the other systems in the car. The fuses for the front and console
power outlets will remain intact and continue to protect
their respective outlets without change. With the front outlet
continuously active, a small solar panel can be easily
attached to maintain the 12 volt battery or for use in jumping the
car should the 12 volt battery become discharged.
Above is a diagram of the rear of the fuse panel and a note describing
the location and color of the wire to place a tap on when adding a
constant power feature to the front power outlet. It also describes
the color of the wire on the rear of the front power outlet where the
jumper will be attached. The pictures which follow will illustrate the
process in detail.
2. Begin by moving the driver seat back and depressing
the emergency brake fully. (This is to give you a little more
room when placing the tap on the specified wire of the fuse box). The
picture above is from the floorboard looking up. Using the diagram
pictured to the left, place a tap on the light green wire of plug 1K,
Pin 2. Now plug one end of your jumper into the tap you just placed on
the light green wire.
Just below the front power outlet is a ribbed insert which attaches
the corner of the lower dash. Carefully remove this insert to allow
the dash to pulled out slightly near the power outlet. This will
expose the connections on the rear of the outlet where you can place
another tap for your jumper.
Peel back some of the tape on the rear of the power outlet to expose
the wired connections. Place a tap on the solid white wire and plug
the end of your jumper (the other end is attached to the light green
wire behind the fuse panel) into the tap on the rear of the power
outlet to complete the installation. BE SURE THAT YOU ARE PLACING A
TAP ON THE SOLID WHITE WIRE AND NOT THE WHITE WIRE WITH BLACK
STRIPE. IF YOU MISTAKENLY ATTACH YOUR JUMPER TO THE WHITE WITH BLACK
STRIPE WIRE YOU WILL BLOW THE FUSE FOR THE POWER OUTLET.
A simple kit has been created for the jumper and
includes the wire taps and jumper with attached connectors. The kit is $10.00+(S&H).
It will take approximately 15 minutes to install and requires only
a pair of needle nose pliers and a screwdriver.
This addition is only for the front outlet and not for the
console outlet. Creating a constant powered source for the console
outlet requires wires to be cut and not a simple
