After reading all the how-to's I did it slightly different on my install.
My goals were simple:
- No special plugs/electrical pins needed.
- Operates like factory, meaning no dynamic brightness, just on as ambient lighting.
- Can buy all the stuff locally.
- No painting/blacking out any bulbs
I have a 2012 (facelift/LCI) with Halogen lights from the factory. These instructions should apply to all facelift halogen 1'ers - not sure if pre-facelift was any different, though I think this method is pretty universal.
To get to this, I tapped into the license plate lights so they stay on whenever the license plate lights turn on and don't dim/get brighter. This is fairly standard to other DIY's, the main difference is where I tapped into for the other end.
You will need:
- Inline splices (autozone/pep boys/amazon) all carry this. You can also use t-taps or your preferred splice method.
- About 10ft of 16-22gauge wiring.
- 8mm socket for removing/installing tail lights
- Phillips screwdrivers
- Flathead or flat trim tool to remove pop mounts
- Pliers
- Zip ties
Locate the wiring loom for the license plate lights.
Remove the passenger side trunk panel and on the top corner you will see a loom of wires.

Locate the Gray/Brown wire. There are two pairs of these with the same color. I tapped twice (one for each taillight) into the slightly thicker one (the other one didn't work, no idea why).

Route the two wires - one will go to the passenger and one will go to the driver side tail light. Leave enough slack so you can run the wires in a hidden fashion. I removed the plastic center trim panel secured by two Phillips screws. Under that there is a smaller trim piece that holds the main power wires so I remove that with a torx driver and routed the driver side wire behind it. I used Velcro wiring tape instead of zip ties.

On each tail light, you want to locate and remove the outside corner bulb. This is the 3-pin connector that others normally modify. I didn't want to find the right pin to use in that connector so I by-passed it and spliced directly into the wire on-board the tail light.

Locate the red wire after removing the bulb and foam seal.

I tapped into this wire with the inline splice.

Re-applied the foam seal.

And test to make sure it functions before reinstalling.
Next I plan on coding out the front turn signals and rear lights so they only turn on when engaged.
