Default 02-03 JDM v7 HID Headlight Install w/ LightWerkz Harness

Just did this in my 03 and couldn't find a complete start to finish write up, so here's my shot at it.

The previous owner installed some Non-HID v7's with a terribly wired retro fit as you will see. I picked up some HID's from a member here and a lightwerkz harness.

v7's:



OEM Ballasts:



Lightwerkz (LW) "JDM STi Wiring Harness" HID for OEM Ballasts:



-(2)Black and Yellow connectors go to High Beam on Lamp
-(2)Black Oval-ish connectors go to factory head light plugs
-(1)Red Eyelet to Positive Battery Terminal
-(1)Black Eyelet Ground to side of fender (Or where ever works best for you)
-(2 sets of 2)Black and Red female disconnects to ballast pigtail


Remove those headlights: how-to

Remove the battery and plastic air induction piece

Now you should see what we are working with, unfortunately my case was a bit different. Check out the previous owners "wiring skills". This nonsense was found throughout the install.




Lets move on,

Drivers Side:

This side is going to use the large portion of the harness, take the black oval connector and plug it into the existing factory headlamp plug. Again, thanks to the previous wiring job, this plug was cut off by the last owner and I had to splice the wires. Therefore I dont have a picture of that for you.

Next, Connect the black eyelet to the ground located on the drivers side fender



Now on to the ballast, Remove the ballast and plugs from the black plate that they are attached to. You will see 4 plugs: two plugged into the ballast, one white 3 pronged triangular plug and a grey plug with two wires (black and blue with white stripe) coming out of it and cut off. These 2 wires connect to the pair of black and red female disconnects on the Lightwerkz harness. NOT the long ones, those are to be ran to the passenger lamp.
Black to Black and Red to Blue/White Stripe

Passenger side is Black to Black and Red to Red/Blue Stripe

These


To These


Now you can either crimp male connectors onto those two wires coming from the ballast or, do as I did and cut the female ends off the LW harness and connect with a butt connector. Either way, connect the wires from the ballast to the pair of black and red female disconnects on the LW harness.

You may notice a small ground wire that was attached to the ballast mounting plate, for safe measure I extended this and grounded it to the fender with the black eyelet.


Now with the lamp still out of the car, run the other two female disconnects to the other side of the engine bay.

Put the Drivers side light into place good enough so it will hold itself in position but don't bolt it in.

Next connect the white three pronged triangular connector from the ballast to its match coming from the lamp.

Like So


Now you can attach the Yellow and Black Plug to the High Beams on the Lamp.

This


To This


Lastly for the drivers side connect to factory plug for the running lights into the connector on the new lamp.

For the Passenger side do the exact same thing with the remaining plugs on the harness

Once you finish that, bolt the lights in place and tidy up your wiring. Place the ballasts in spots where they wont move around.

The final step is to put your battery back in and connect the red eyelet from the harness to your positive battery terminal.

Enjoy the JDM goodness.

I'm really happy that you posted this when you did! I have a set of HIDs on the way and was trying to find a nice, condensed, pic-filled write-up. Thank you so much!

I plan on doing the LHD conversion on my lamps, along with the electronic leveling motor, and I would like to link to this thread once I create that how-to.

I just got my jdm hid headlights in. I've never installed hid's before but obviously my bugeye didn't come with them. Do I need a plug and play kit or just cut wires and match accordingly? I can't believe there isn't a sticky on this *#%^.

Look into wire harness from lightwerkz.com and if your not going to swap the reflector plates they will do it for you or do a TSX Retrofit.

Anyone know the answer for this? Is a plug n play harness needed or can you hook it up without one? I think the high beams may be an issue without a harness

I hard wired everything and I do have an issue with no high beams. I am going to rewire it all one day but for now it can stay the way it is. Somehow daytime running lights (previously disabled) keep going on and off when the lights aren't on at all.

I unplugged the connector. When we ran the new wiring, I think my buddy grabbed it and connected that again. Now my lights are on as long as the car is on unless ebrake is pulled. I can't wait to have some time to re-do it all. I am just going to pull everything out and start fresh with a wiring harness this next time.

What are the pros and cons of having a wiring harness vs not?

Con - Ending up like me from a DIY gone bad.

Hmm well I took mine to a shop the other day to get mine installed and they got the high and low beams hooked up and working right. I disabled the DRLs to be safe via under the glovebox. I'm a noob with lighting so I'm pretty positive there was no wiring harness in what I gave them but they wired it all up professional so either they made one or got them to work some other way. PO had put some HID bulbs w/ ballasts into stock housing.

I installed my jdm HID's last night, using a Lightwerks harness. I also used these instructions, since the harness came with none. (Really appreciate this thread.) Everything works properly but the low beams, (projectors). I opened the fuse box and saw the 30AMP fuse is broken. When I look at the wiring coming from my oem ballasts, (Which are the same ones pictured), the black, square plug, (not the grey plug w/triangular end), has a brown and orange-ish wire, as pictured, but it is not connected to another plug with a black wire and a blue wire. On the driver's side, I currently have the black female connector on the L.W. harness attached plugged onto the male prong on the brown side and the red female attached to the male prong on the orange-ish side. Same on the passenger side. Should I try revering this since the fuse blew?

Sorry yo bring up such an old post but im currently doing the same thing and the same thing happened to me. The fuse blew. Can anyone help us get an idea of what to do. As the socket that came with my ballast did not have the socket where theres the black and blue wire. Any help would be greatly appreciated
