I just installed the foglight kit. The oem wiring harness comes with the instructions. There were a few things that the instructions failed to mention. Wasted about 1 hour of my time.
Below are a few items that you need to be aware of.
1. Once you take the fuse box apart and inserting the red wire. It won't go in unless you unlock the fuse box. Meaning, you need to take a picture of the front of the fuse box. Remove all of the fuses. The on the back, the purple bracket needs to slide 1/8" to unlock, then you can insert the red wire into the fuse box. Location 37.
2. The wiring harness itself where all the connectors goes to the inside of the car. You need to cut the tape back, so, you can have more slack with wires going to the fuse box, the black connector. above the brake pedal to the left.
3. If you didn't want to sped $20+ on the pin connector tool. I used 2 small cotter pins. I flattened the tips out with my vise, then ground the sides down with a dremel. Worked perfect. Slid each of the cotter pins into connector #5 and it came out easy.
4. The wiring for the passenger side fog lamp, on the instructions goes right above the turbo. I'm like, why would you route your wire above that heat. So, may need to extend the wire and route it around the front of the car.
