Take a look at the back of the angel eyes...
There is one large plug for the headlights main beam.. that is a straight swap for your original headlight plug...
The indicators, the bulb holder comes with the angel eyes... twist it and it comes out... then you can twist in the bulb... they are plug and play with your original indicator wires...
You will have one loose wire that was originally connected to your electric beam adjuster motor... these are not needed, as angels are manually adjusted... so these can simply be taped up...
You need to decide firstly whether you want to have your standard sidelight bulb fitted aswell as the halo rings and the LED.. if so you will need to take the holder out your original lights and put them into the angel eyes...
Crimp the ends of the three red wires together.. and splice them into the positive (red) wire of the sidelights...
Crimp the ends of the three black wires together and splice them into the negative (green) wire of the sidelights...
Make sure you test all of the lights before fully securing them back into the car...
Hope that helps!
