I recently purchased this and yeah it is very simple to install once you clearly understand the car/specifics to the year, and whether you are installing the electric headlight eyelid cover motors. If you are just installing this kit itself, it is pretty much right out of the box and follow the instructions. They are easy to hide, run the wiring, simple plug in, and then install the connection point near and to the starter solenoid. See pics. In this installation I decided to install the electric eyelid motors also. I installed those first, and then placed the relays where I wanted them and ran the wiring. Then I reconnected my grills (partially moved them for the eyelid motors) and did a quick connect of the oem connection points and the starter solenoid. Here is the one thing I didn't catch but figured out later. When you connect both the relays and the motors you MUST put the relays in connection AFTER the motors or you will see weird stuff like doble blink covers, open and then close eyelids, or in my case open and close and reopen when you hit the high/low beam switch. once i did that all was perfect. no eliminating wires, etc. In my installation I had virgin OEM wiring still in place with all correct connections. Yes, you will see brightness in the headlights, and an unexpected extra...I saw an increase in the brightness of the OEM dash gauges and their oem type blubs.
