Basically what you're doing is converting the center parking lights into brake lights.
My method
Pros: quicker, easier, requires virtually nothing
Cons: definitely not as bright as yours
If you want to know what it's going to look like beforehand, have someone or something hold down your brake pedal, and turn on your parking lights.
For mine all you need is 2 inches of 18 gauge stranded wire, some solder, and a wire cap. Take you less than 10 mins if you put the damn beer down for a minute (I wont).
Pop off the backside cover of your trunk. Leave your hatch cover alone.
On the right side you will see a plug connector where the hatch wires exit through the grommet.
Cut the red/blk parking light wire in two. Cap the car side off.
Extend the hatch side of the wire a few inches.
In the harness just below the plug connector is another wire bundle. This bundle contains two grn/wh brake light wires. Strip back some insulation and join your extended wire to one of the brake light wires.
THAT'S IT!
PS, you can still swap out the bulb sockets for larger ones and just connect the wires to the red/blk wire and blk ground wire of the smaller sockets.
