quick question.. if these are bixenon projectors, what about if i put them in my 05 headlights since the 05 headlights have separate bulbs for high/low beam? i know its been done, found another thread for it. im just curious with how it works.

you can have double hi beams. just wire the solenoid to the existing halogens.

I know I' m bringing this post back from the dead but I was looking at my Minis and HIDs and this is the first time I do anything like this. I understand everything when it comes to installing the minis and placing the HIDs.
However, nothing was mentioned about the high beam wiring :S kinda confused by that. I'm no engineer so the diagrams don't help me too much (though I can understand them a bit, I just get lost at parts.)

EDIT: K so i just did some more in depth reading trying to figure it out. I want to make a connection (like a wire? what should I use?) between the high and low ground so both are on at the same time. Is that correct?

well first you need to make a new wire harness for the hid bulbs (for lo beam, but hi beam uses the same bulb and just lowers a shield in the projector to expose more light). the hi beam solenoid is very low power and can be tapped to the stock hi beam wires. pretty much you can use the wire harness i made for mine. except instead of the hi beam bulb, you will have the solenoid with the two wires.

pretty much you need to make this circuit. go get some 14 gauge wire (bulk) like black and red to tell power and ground, grab a fuse holder and 15 amp fuse (for 14 gauge wire), get some ring terminals to connect the power wire to the battery terminal and the ground wires to the chassis, get some heat shrink tubing, a soldering iron and solder, and heat gun (for the tubing) oh and lots of zipties from home depot and radioshack. just start from the battery and work your way to the ballasts slowly asembling the wiring. leave the fuse taken out until everything is finished. for every connection, use a heat shrink tube or two after soldering the wires together. then put wire loom over it. this diagram works only for 01-03 civics.

I got a wiring harness from DDM with the HIDs. I layed out my wiring harness on my bed and plugged the ballasts and hids and layed the minis by it to get a visual of what it will look like in the car. It has everything your diagram shows, but one more thing...

What it looks like is the wiring harness has a blue and black wire for hi/low... which makes me think if the bulb itself is bixenon... It looks as if it has 2 filaments? Is this normal for HID's or do I have a bixenon bulb?

I think I may have bought the wrong HID kit... :S

i personally would throw away that harness and make your owm using quality components (and bosch relay). ive seen all sorts of problems with cheap aftermarket wire harness. and my harness allows the lo beam to stay on when the hi beam is used. im betting your harness doesnt and when you switch to hi beam, the hid will turn off. hid bulbs are only "one filament" so to speak. it either lights up or not. any pics? the bulb should plug directly to the ballast, then the ballast plugs to the wire harness with a + and - wire for power and ground.

Shift-E

I'll upload pics when I get home. The bulb does plug directly into the harness. But then there's 2 extra wires (Blue and Black) which I assume are for high beam?
I probably will make my own harness. Will probably be more reliable like you said, and if anything goes wrong I can just blame myself. There goes 12.50 for the DDM one :P

Shift-E

Ok, so I took some pictures. I have the harness, the bulb, the ballast and the mini. I took a picture of the bulb alone, one connected to the ballast, and one connected to ballast/harness.

It's the blue and black wire that are with the bulb that I don't know what theyre for. I'd assume to plug into the H4 plug, but why would I need that if I'm not using the bulb for hi/low. If i plug it in without that then the bulb would be on as soon as I turn on the car wouldn't it? At least thats what I understood from your diagram. So my only guess would be that they're for hi/low. Or maybe I have that wrong, it is my first time doing anything like this after all. :S

Let me know what you think.

um i dont know what to say about that lol. the two black wires coming directly off the bulb need to go to the ballast. not sure what the other two wires are for with spade terminals. like i said, its best to make your own. that way you can build it to the engine bay so it fits perfectly. ive never been able to properly install even a good quality harness because it requires precise measuring and running the wires around holes and curves. with my diagram, remember the harness trigger wire (86) to the H4 +12v headlight wire is OFF unless you turn the lo beam or hi beam on. only then will the relay energize and send power from the battery to the hids. this is the common power which you need to tap to keep the lo beams on in lo beam and hi beam mode. if you tap one of the other two wires, they will only stay on in lo or hi mode but not both since its a switched ground system. for example, the HI wire is hot when the lo beams are on (so that the hi beams stay off because there is no ground). then when you switch to hi beam, the HI wire becomes a ground (and the hi beams turn on since they have a ground and the power from the +12v wire). +12v wire is hot in both lo and hi beam mode. the LO and HI wires switch from hot to ground depending on the mode youre in. there is no other way you should be wiring them, esp since you need the lo beam to stay on in hi beam mode.

also if its not clear in the diagram, the relay is for the passenger side only (since its closer to the battery and stuff). notice the main (30) power wire goes to both left and right ballasts. i did this for simplicity, but you could technically make the same thing on the other side too with another relay for the second ballast. this requires another relay and more wiring but ensures that if one relay fails, the other side remains on (so you have one headlight to drive with). with my one relay, if the relay goes out there are no headlights. for me i dont care, because i have separate halogen hi beams wired off the factory harness i can flip on in an emergency. bosch relays are pretty reliable and so far for a year ive never had isues. but you never know.

So after doing some research I found out the spade terminals are postive and negative that OEM H1 bulbs usually use. So i got to thinking, if its just a positive and negative wire then would I be able to splice the wires from the projector to those and plug those into the H4? Then the wiring harness would look basically exactly like yours. It's just the wire thickness is different. Would that make any difference?

Since I have a wiring harness that looks pretty okay, I wanna try it. Then if I have any problems I can make my own.

What do you think?

you really should have 14 gauge wire for hid. 16 would work, but over time the wire will eventually fail from too many surges (startup draw). and im not even sure what you would hook up, its very difficult to figure out what that harness is doing. not to mention you do not know the quality of the connections or the relay. so it could just fail one day for no reason. you should only have one wire going to the h4 plug and thats the harness trigger wire to the +12v headlight wire.

Shift-E

Wow I just realized the harness that i got is 20AWG... Def making my own now. I need to spend a lot more time on this then i expected.

So parts are:
Bosch relay (is there specific name for this relay im looking for? one with 30/85/86/87)
14 AWG wire (how much wire should I be buying?)
15 amp fuse with holder
ring terminals (2? one for battery, one for chassis ground)
heat shrink tubing
wire loom
Spade terminals to put into the H4?

How do I get the plugs that go into the ballast? are plugs like those available at home depot/radioshack?

E®ik

I just thought of an idea. When you get this all figured out, maybe you can come do mine lol

jokes.

So looks like I will be going the MH1 route instead of spending a stupid amount of money on an Acura retrofit.

Shift-E

Lol, I can def help if you need it. I forgot to update this post. I've got mine all done, up and running since may with no problems.

I'm a complete noob at this.
In fact, I just started looking at repairing and decorating a car that's been sitting on the driveway for 3 years.

I've got a '98 DX.
Given what I've read so far, my concerns are wiring and fitting.

Guess I'll do more research when i have more time.
I'm open to tips too!

MindBomber

Hey, another person from Vancouver

The wiring and fitting with MH1s isn't difficult, even for a beginner.

you didnt mention about how did you run the wire for high and low beam i just bought the same retrofit from theretrofitsource.com and i have hid kit h1 can tell me if how did do it ?

x2. looking into doing this atm... but not sure how to wire the high beam either -__-

if you have 01-03 civic heres how i did mine. the lo beam needs its own new harness you have to build. the hi beam bulb OR bixenon solenoid can use the stock wiring (for hi beam). www.partsexpress.com has all the ring terminals and bosch/tyco relay and fuse holder you need. its very simple and the hard part is routing all the wiring cleanly and soldering/heat shinking the connections. taking off the bumper is a must. the relay trigger wire 86 for the hids only needs to be tapped to one side +12v wire (i cant remember which side is red and which is red/yel but the battery side passenger h4 connector is easier). the solenoid/hi beam bulb needs to be wired separately at both sides directly to the stock h4 plug wires. the wiring used for 30 and 87 connections need to be heavy 14 gauge. the 86 and 85 can be thinner because these are low voltage triggers for the relay to open and allow power from the battery to reach the hid ballasts.

Well i just bought the entire kit from The retrofitsource. It was plug and play and my highbeams and low beams work correctly. Two thumbs up for them.

x2, just finished mine as well (:

I just used The Retrofit Source as well. I bought the Morimoto Mini Stage 3 D2S kit from their website. I bought the complete kit.

Here's pictures of the retrofit and the OEM headlights

Those look sick! But why the D2S and not the H1? Most people ive heard recommend the H1 over the D2S

KurtzN1

Looks great! That's next on my list.

localkineguy

Do you know if this is the same for the 6th generation Civic? I notice that the 12V terminal changes between low and high beams turned on. When the highs are on, the low's 12V becomes 0V.
Also what are the proper specs for aiming the headlights? What sort of angle should the cutoff be at?

f22prelude

Yo I'm wondering if you ever got around to making the scheme for the regular wiring harness.

I put some ddm ballasts in and wiring them correctly but when I flip on my lights I seem to be getting either only lows or only highs I can't tell since they wont change.

Played with the harness on the ddm side but I can't get anything.

After a long google hunt I came across this old post where it says you need to install a diode, just wondering if I could get a hand/assistance with getting this done.

Thanks peeps.

;one thing that lots of guys wonder (myself included)
Where to mount the relay harness and ballasts.
My choices below:
Ballast: under the headlights, where the frame mounts to chassis:

Relay Harness
under the battery tie-down and radiator/headlight frame (Near the fuse box, I have a DRL Hamsar unit... And the other side of the battery, the SRI Air filter is on the way...
