    I need to install an aftermarket GPS "tracking unit" somewhere in the Prius.

    The unit is small, about 4x4x1 inch. It requires very little power, but needs to be close to the dash or rear hatch for antenna mounting (antenna goes behind glass on inside of vehicle).

    The unit needs 3 electrical connections, ground, +12V all the time, and +12v when car is on.

    Where is the easiest place to grab power from? I know the Cig plug is +12v when the car is on, but what about +12v all the time in the dash area?

    Or, if I mount unit in back, where to grab hot and ign on power in the trunk area?

    advice please...

    If you mount it in the front you can grab "power always on" from the fusebox under the hood - the jumper terminal. Be sure to put an inline fuse as close to the jumper terminal as possible in your power wire. "Accessory power" is from the cig. lighter or from the aux. power in the console. Again, put in an inline fuse as close to the power pickoff connection as possible.

    If you put it in the rear you will have to run the "accessory power" from the console back. I used a plastic loom and ran it beside the "hump" in the centre of the car (under the carpet). "Power always on" can be picked off the battery in the right rear. Again, put inline fuses in both lines as close to the power pickoff point as possible.
