Hey everyone! So recently, one of my low beams in my headlights died, so I figured hey! This would be a great excuse to finally get HIDs! And that's exactly what I did. So here is a full list of what to do when installing the HI/LO H4 HID kit from DDM Tuning. And the kit I specifically got was the 8000K 55W HI/LO HID kit. I wanted to get a nice, bright, white color for my lights with a tint of blue in them and normally, an 8000K kit would be a lot more blue, but that is only if it is a 35W kit, when you get a 55W kit, no matter what bulb temperature you go with, the 55W kit will flush out a lot of the color, but is also a lot brighter. So for me, it works perfectly, because I was able to get a perfect match to my LED mirror lights that are a “cool white” color.

Before


After


Here is a picture of the kits contents right after I opened the box.


This is a picture of the HID harness and as you can see, it says H4 for the type of bulb and then HL for the HI/LO function.


Here is part of the ballast where it says that it is a 55 watt kit and that it requires a 12 volt power source.


Here are before pictures of the stock FJ lights, sorry the pictures showing what they look like on a surface are orangeish, my camera would go to sunset settings
DRLs



Low beams - as you can see, one of the headlight filaments are out



High beams



_________________________

Now for the instructions, first, start with drivers side headlight


Unplug the OEM headlight plug just by pulling the plug straight out


Then remove the rubber weather seal by pulling on the tab


This shows what the headlight housing looks like from the rear after you remove the seal


Now you are going to want to unclip the metal retaining clip which holds/locks the light bulb in place


Then just remove the OEM bulb or whatever previous light bulb you have installed - after this point, I highly recommend wearing gloves so that your skin doesn't come in contact with the HID bulb, any oils that contact the bulb from your skin can ruin the bulb


Here is a picture showing the dual filaments within the stock bulb, this is how the one headlight can have both high and low beams in case you didn't know


Now, carefully remove the foam protection from the HID bulb




Now just install the HID bulb into the headlight housing, the metal shield attached to the bulb will be on the bottom side when you put it in, then you just reclip in the metal retaining clip so the bulb is locked into place



Now run the wires from the bulb through the weather seal and then push the seal down around the bulb

Next, you're going to take the HID wiring harness and you're going to hook up the positive and negative connections, start with the positive red wire and then hook it up directly to the battery



Then attach the negative connection to the battery's ground connection



After this, you're going to take this plug from the HID harness, and your going to plug it into the OEM bulb plug




Now grab one of the ballasts


And you're going to plug this plug from the ballast into the matching plug from the harness



Next, you're going to be plugging in the plugs from the ballast into the plugs from the bulb



Then you'll plug in this little plug that is right next to the AMP plugs you just plugged in. This is what enables the HI/LO function



Now you'll just repeat what you did on the drivers side for replacing the bulb, but on the passenger side



And then you just connect all the wires on the passenger side exactly like you did on the drivers side



And as for the ground on this side, just make sure you attach it to the frame somehow, I did mine on this bolt on the windshield wiper fluid reservoir since it goes into the frame


After you secure all the wires, ballasts, etc. then you're ready to go!

Just some side notes - as for the OEM plug for the passenger side, this becomes useless so you can just tape it up and do whatever you want with it. Also, as for my day-time running lights with the HIDs, I installed a switch about a week ago so I can turn off the DRLs unless I want them on for something specific like highway driving or dusty roads or whatever.

Here is a link to DDM Tuning's website: http://www.ddmtuning.com/

And as for my LEDs in my mirrors (and any other LEDs in my rig), i went with superbrightleds.com. And I specifically got the 194 LED Bulb - 6 LED Wedge Base, and specifically, the product code is WLED-x6 and the color I chose what the cool white color so it does have a blue hue too it and that's what I wanted to match with these HIDs, and in my opinion, I nailed it!

Here is a link to their website: http://www.superbrightleds.com/

And here are some more before and after pics, and don't worry, soon enough I'll get some comparison pics with my FJ right beside a normal FJ showing both of the lights looking both at the FJs, and looking at the beam pattern from the FJs and the light they throw out.

Looks real good. I'm going to have to order me these. Did you get or see a need for the mounting brackets?

Thanks for the awesome write up man!! I'm going to be doing this very soon!

I have 3 of their kits- 1 pair of 35watt 5000k and 2 pairs of 55watt 5000k in my hella 500/700 housings and you really can tell a difference in the color of light.

Once again nice write up!

Great job, love the consistency between the mirrors and headlights. Do you have nay pictures of the ballast mounting location. I am concerned the wiring is a little shot to do a proper mount hide job. How did you hide / mount yours? Thanks!!!:clap:

sorry but IMHO these are hazardous to oncoming drivers and have poor output. check out some projector retrofits with bixenon.

Hello, Just installed my HIDs and I was wondering where did you brace your ballasts? Did you just leave them hanging or did you secure them to the frame somewhere? Thanks for the Forum... it was awesome and very detailed.

the 55 watts are to bright and will get you stopped by the cops i recommend going with the 35 watt kit with the 8000K bulb...even the 6000K are to bright with the 35 watt kit...35 watt 8000K perfect
