Hi,
This is my first guide so please if something seems unclear message me and i will try to explain better.
Sorry for the quality of the pics my camera died and had to use my phone.
1st you need to remove the 4 screws and take the back plate off of the camera.
2nd cut the back plate to remove the wire.
This is what it will look like when done.
3rd cut the plastic strip off your licence plate lamp.
Then cut the bulb holder off. I forgot to take i pic when i did this.
Push the leads through the newly cut licence plate bulb holder.
Then align the bulb holder with the camera and make small holes in line with the screw holes in the back of the camera and screw them together.
Then fit the seal back to the light.
Then i soldered the lamp wires in the camera for the licence plate light to the cut off lamp holder so it can just be clipped together in the car.(easier to remove if you need to)(dont forget to tape the end up as to help secure the wire and stop any problems with it shorting out on the body)
Make sure you get the correct polarity for the led or it wont light up.
Then fit it to the car.
Then check it works.( the camera i recieved the leads for the camera power was coloured wrong i had to rewire them red to negative and black to the possitive.) i thought the camera was broken.
My head unit is the pioneer AVH-2400BT.
I hope this is of some use to someone on here and thanks for reading.
