I had to add diodes to my '05 when I put LEDs in the dash. A couple in the 1N400X series (replace X with digit) are fine. They're one amp diodes, which is way more than enough, and the last digit indicates their voltage rating. For 12v use, they're all OK, since a 1N4001 is good for 50v and the others go up from there.

Add a wire to connect ground to the negative side of the LED, and put in two diodes, one from the left wire and one from the right, with the banded ends together and connected to the positive of the LED.
