Install and Review of XenonDepot 4300k HID kit for 2006 4Runner

After much research, I finally decided on an HID system for my new 2006 Sport Edition 4Runner. Based on opinions and reviews from people on this forum and the Lexus GX470 forums, I decided to go with XenonDepot for the kit. There are other companies providing similar HID upgrade kits, but the quality of parts and ease of installation of XenonDepot's kit seemed above par compared with everyone else. Plus, most of the Lexus guys have installed XenonDepot kits and still talk highly of them, even after a couple years of use.

For those interested, the correct kit for the 06 4Runners is XenonDepot's H11 kit. Since our 06s come with projector headlamps from the factory, no retrofit is necessary. This makes the install way easier and very clean. XenonDepot takes Phillips Xenon bulbs and mates them to an H11 base, which is how our stock halogen bulbs mount into the headlight housing.

On the topic of bulbs, there are a couple options within this application, such as 4300k or 6000k. Simply put, these ratings are based on the color and relative light output of the bulbs. Here's what I debated between:

4300k - these bulbs are most common for vehicles with factory-equipped HID systems, for example, a Lexus RX330. The light output is greatest (you will see farther) and the light is a bright white with a slight hint of blue at the cutoff.

6000k - these bulbs provide more blue color in the beam, but have slightly less light output. Although they may have slightly less light output than 4300k, they are still way better than the stock halogens, so the choice will depend on your personal taste. Most of the GX470 guys went with 6000k and were very happy with it.

I picked 4300k because I wanted that factory look and the best possible performance. I'll get on to the post-install review later...

Back to the kit and its contents - in addition to the rebased Phillips xenon bulbs, the kit includes Phillips slim ballasts, ignitors, and a plug-and-play wiring harness with an inline fuse. The wiring harness has connectors that snap firmly into place with both your stock harness and included ballasts. The fuse is designed to protect your factory harness from drawing too much power during startup. Although HID systems draw less power than Halogen during operation (35W vs. 55W), the extra power needed upon startup to ignite the salts in the Xenon bulbs could damage stock wiring if not protected. This kit has you covered with no extra parts needed.

Here's what the kit looks like:

Radiator support with plastic trim (this trim will be removed later for access to run wires across to passenger side)

OK, enough of the BEFORE pictures. On to the install!

First step is to disconnect the battery:

After disconnecting the power and ground to the battery, carefully pull the battery out of the engine bay and set aside. It's heavy so be careful not to drop it on that nice paint job!

Here is what the rear of the driver side headlight looks like with the battery removed.

After battery is removed, remove the stock harness connector from the driver side H11 bulb (low beam, closest to fender). Be sure not to cover up this connector; it will be used to connect to the XenonDepot harness later.

Now disconnect the harness connector from the bulb on the passenger side headlight. Since this connector will not be used to connect to the XenonDepot harness, you can seal it with electrical tape to protect it and keep moisture out. After that is done, go ahead and remove both of the H11 halogen bulbs from the headlight housings by twisting them counter-clockwise.

Now comes mounting of a ballast on the passenger side. I mounted mine on the inside surface of the vertical bracket for the power steering reservoir. This kept it low and out of sight unless you are looking for it.

First, attach one of the large pieces of double-sided sticky tape (included) on the rear of the ballast and press it firmly onto the inside of the bracket.

Another angle.

You may notice I installed the HID bulb into the headlight housing during this step. When you do this, be careful not to touch the glass bulb, as your skin oils will cause the bulb to fail early. If you accidentally touch it, wipe the glass with alcohol to clean it.

After twisting the bulb into the housing, move the two wires out of the way. You will connect these later.

Use zip ties (included) to wrap the ballast against the bracket. The double-sided tape actually seemed strong enough to hold it, but I figured the zip ties would ensure it would stay put if the tape ever failed.

After securing the ballast, mount the ignitor on the outer surface of the bracket using a small piece of sticky tape and zip ties. I mounted the ignitor with the single wire facing down and the two wires up.
