Wiring Sidemarkers/LED mirrors
For UK laws, my car was fitted with LED side markers. This info should be great for anyone looking to do an LED mirror or side markers.
1. The first step would be to remove the front bumper. By doing so you can expose the wiring that leads to the headlights.
2. Locate the green wire on the driver side. The passenger side is green and yellow.
3. Back the headlights you can find two bolts. You can use either of the two bolts for a ground.
