I was playing around with my oscilloscope one day and scoped the DRL/Highbeam and Low beam lights... All of them run on a duty cycle, which explains why an HID kit doesn't simply plug in and work. I wonder though how a relay kit solves the problem? If the relay trigger is duty cycle, won't the relay also flicker? Or is it too fast for the relay to react?

It's actually not a relay, it's a capacitor and voltage regulator. It stores power and tricks the system into thinking it's the factory bulb and in turn feeds a constant steady voltage to the hid kit. The down side to this is you are not getting full power to the HID kit because it would just keep discharging the CAP if it were sending all the power, but because they are HID's they are still brighter.

Ahhhhhh, well that makes sense! Genius! When it comes time, I'm sure I can figure something out, and if not me, my friend's an electrical engineer/genius. Nothing is coming to me off the top of my head... Although a relay has two high amp outputs, 87 and 87a, one is normally open, and one is normally closed. If you use both outputs to supply power to the HID's, it should feed power to the HID at all times cause either with the relay off or on, each line will alternatively be energized. No?

You'll have to go through the fenders. You'll need to move the fender liner (Philips heads) via 4-6 screws and the entire front corners become available (entire removal is not necessary). There are 2-3 screws in the fender area (front part of the wheel well) and 2-3 more under the front of the car. You'll need to turn the wheels to get to the screws and have enough room to work. Once the fender liner is loose then you can get to and upgrade the foglights. I'll try to take some pics and get them uploaded.

Under car screws

Here's a pic of the 2 screws under the passenger side foglight. Same thing on the drivers side. My camera couldn't get a good shot of the 3 screws in the fender lining. 2 screws face towards the engine and the other at the top of the fender, against the inside of sheet metal.

Vsx1 HID wiring

Here is a pic of the wiring near the battery. The front HID relay is in the upper left quadrant of the pic. The foglight relay is in front of the red dot on the air filter box (not shown). The passenger side ballast is behind the passenger signal light above the black bolt (upper right). If you follow the red wires to the lower right, they go into the headlight assembly.

Not quite. 0.75"-1" holes need to be drilled into each duster cover behind the headlights to allow the wiring harness access to the bulb(s). The covers just twist off. Then attaching the harness to the battery, again simple. After that it should be plug and play. There are no mods for the fog lights other than the hookup to the battery (2013-14), as there are no dust covers.

Here's the URL for the video:

It is helpful if you can make it as a step-by-step guide with pics and texts.

Good Good Study,Day Day Up!
