This thread is great and the only one of its kind I can find! But i was wondering if you could give me some more info on how you actually wired it up?
Also, I see that you’re projector was for H1 bulbs but you used a h4 Ballast. Did you have to modify the projector in order to get the bulb to fit? Was the bulb you used dual beam or was it a single beam bulb?
I’ve been trying to wrap my head around doing this with my spare set and it’s driving me insane.
Trying to revive the thread
The H1 bulbs are completely unrelated to the H4 connection on the harness. There is no such thing as an H4 ballast... Ballasts all have standard connections, it's the driver to fire the bulb. The projector was an H1 projector, which takes H1 bulb. Also, Bi-Xenon (which this entire thread is based around) means that the projector has a shutter mounted to it which is used to execute low and high beams. Dual beam bulb? no such thing...I think you're referring to when you use a single bulb which is moved to change the low and high beam and is magnetically activated. This thread is not utilizing a single bulb which provides high and low, that's mostly for people who have 1 single bulb that pulls high and low beam duties. They put them in standard housings, which is a big no-no.
I covered the wiring pretty thoroughly on on page 2 of the thread, what exactly are you having trouble with?
I'll try to break it down a little bit.
The H4 HID harness is the controller for the entire HID system.
But, the harness needs power when the headlights are turned on to activate the system.
You'll notice with the H4 connection on the harness there is a powered hi and lo wire (s) and then there's a common ground.
On your car OEM, when you turn on your headlight switch, it sends low beam power to the internal harness within the headlight housing, to the low beam plug. This lights up your bulbs. You need to "harness" the power of this low beam signal and send it to the "hot" low beam wire on your harness.
This was the 2 pronged grey and black plug that goes into your low beam plug within the housing. The black wire will be grounded, the grey wire will be tied into your "hot" low wire on the harness.
Now, when you activate your high beams via the stick on the column, it also sends power to the high beam socket/harness within the housing. That's where the red wired splitter comes in. Make it easy on yourself and just plug 1 end into the high beam plug to draw that power....then plug the female side of that into your LED bulb or whichever hi bulb you choose. Connect the "split" section of that to the shutter on the projector. Now when you activate hi's, you'll have the high beams on the projector and the OEM high beams come on. Very good for dark backroads, but honestly, the HID high beams are so bright they drown out the LED high beam bulb I have. Even on my truck, my H1 highs drown out my light bar...they're that bright. So it's up to you if you even want to use a high beam, but I did...in case for some reason I lost the harness relay (and lows), I'd still have high beams to get me home.
If you do it this way, nothing will connect to the "hot" high beam wire on the relay harness because you are not using the high beam portion of the harness (ie you don't need to provide power to the high "hot" since your high beams and projector shutters are all being activated by OEM power).
Hope this helps
