How-To: Create a 9006 to H1 Conversion Adapter, For 9006 bulbs converting to OEM projector Options

[ILoveMySilly97]

i got a H1 harness but it only have one black wire. is that the wrong one? where can i get the correct one? looked everywhere and thats all i can find. i saw a H3 but it has 3 black wires, i figured it be the same as the as the one i got.

I'm assuming this is for the projectors. It'll be easiest for you to just do a HiD conversion. Use a 9006 ballast and a H1 HiD bulb. It'll all be plug and play.

is it gonna b for my celica? or do i need to h1 conversion? i am not an expert at these lighting stuff

Only with certain kits. My DDM Tuning kit, for instance, still required me to make one of these harnesses. The kit I had before this DDM kit (can't remember the brand but it was much higher quality) was exactly the same way. I can't remember off the top of my head how it was wired up but I think I plug the bulb itself into the car's harness, not the ballast.

The usdm Celica came with 9006 harness. If you have the stock lo beam then you dont need any conversion. Only time you'll need a conversion is if you're upgrading it to something else. Like the most popular jdm projectors that uses a h1 instead of 9006.

Richee is right. The kit I used was hipropower off of eBay. It had I believe one wire from the car to the ballast(this is the 9006 wire that you'll want) and the other two is just the hot and ground wire from the ballast to the bulb.

Silly is correct. HID kits plug the harness from the car to the ballast, NOT the bulb. The bulb only uses power and ground (round plugs) to the ballast, and sometimes come with a wire or two if they're of the hi/low kind.

i am converting my headlights to the jdm projectors. so i should just get the kit then correct? and it should already come with harness the converts the 9006 to the h1 right?

Here's what I did:

Got my H1 Hid bulb inserted in the housing. I used LewFX method to get my HiD's installed.

I used UTSlickVic's method to connect the accent socket. Just need to splice the other end into my parking/turn lights.

I'll go into more detail since I'm on the computer. Here's what I mean by 9006 ballast and h1 hid bulb.

9006 Ballast: Reason is because your stock harness is 9006. So you buy the 9006 ballast which will come with a 9006 wire that'll plug from the stock harness to the ballast. Now there's electrical power from your stock harness to the ballast.

H1 HiD Bulb: Simply because it's the size that'll fit the projectors. The bulb will fit the projector housing. Now the other end of the bulb will have two wires attached to it. One hot and one ground wire. They'll both connect to the 9006 ballast. Now you have power from the ballast(^ballast got power from the stock harness^) to the H1 HiD bulb.

So basically once you have a 9006 ballast. Theoretically you can attach any other type of HiD bulbs to the same ballast. You can say it's kind of/sort of an improvised 9006 to universal conversion adapter.

Silly is correct. HID kits plug the harness from the car to the ballast, NOT the bulb. The bulb only uses power and ground (round plugs) to the ballast, and sometimes come with a wire or two if they're of the hi/low kind.

Mine do. The bulb harness has 4 wires. 2 go to the car's harness (hence the need for the H1 conversion harness) that lead back to a generic plug on the ballast, then two more wires that lead back to the bulb itself. Both HID kits I've had we're wired up this way. It keeps the ballasts universal so all the manufacturers have to change is the bulb. I know other brands plug directly into the ballast, but I can't say I know which brands are wired which way. It'd be nice to get a list going so we knew which kits to buy and which kits need this H1 conversion harness.

Edit: Finally found a picture that shows how my kit is wired up. The car's harness plugs into the bulb, which has the specific bulb plug (I.e., 9006, H1, H3, etc.). This then uh's into the generic ballast, which is universal for any bulb type that DDM sells. Then two more wires, the positive and ground wires, lead out of the ballast and plug back into the bulb via more generic plugs. Tacky, but I guess it keeps cost down for DDM.

Been trying all day to source the parts for this....
My Projectors came with the H1 connection and the plug, but no shop in my area has a Female HB4 (9006) socket OR a HB4 Harness kit...
On eBay I might as well just buy the complete H1 to HB4 adapter from Hong Kong...
It is a lot cheaper than buying the parts off eBay separately...

Called every single car/auto dealer around my area... No one has the needed harnesses or plug

I guess my only options are to:
1) Splice into OEM wiring
2) Buy a new plug set and redo a whole new plug setup or
3) Buy the Wiring adapter from Hong Kong and use it

I will probably just go with 3), since it is the cheapest and easiest... I just hope the adapter is not going to ruin anything or burn out

If you splice the OEM wiring. Keep the 9005 end. Take it apart and you can can use the connectors to connect to the accent plugs. ;P

I don't know what I am gonna do, don't want to wait for an adapter from Hong Kong, and don't want to splice my wires...

On a side note for these JDM lights and people fitting them to their Celica's, in my home town of Canberra, Australia, these lights will not pass rego! I was informed that these lights need to have a leveling system in them, they cannot not be fixed in place so that you can blind others drivers. I thought it was a bit slack but those are the rules here in Canberra, so if you are planning to get your vehicle registered in Canberra with these lights, remove them and fit standards and then put them on after. Hopefully this will help you avoid the issues I had with ACT rego

Cheers

To clarify you WILL need this adapter regardless if you have HID's already or not. I previously had HIDs in the stock housing (yes, shame on me), and just received my projectors. I didn't order this harness based on what I read in this thread. But to confirm, you WILL need this harness. The bulb will have to plug into the car, so an H1 bulb into a 9006 vehicle will not work.


I've also had difficulties finding these plugs locally. Can't seem to find a female 9006 or a female H1 plug, and ofcourse no one is going to stock the adapter harness.
Looks like I won't get these installed this week, unless I go to the wrecker with a shopping list of cars that use and H1 headlight, and a 9006 headlight, and hope that they still have the plugs left.



EDIT: Well, after scrambling around the city to find the parts I needed to build this adapter harness. I realized I didn't need it, as the thread mentioned. I previously had 9006 HID's. I was able to use a combination of the new HID bulb and pigtail, along with a pigtail from my existing 9006 HID bulb, and make it work.

Lesson learned, if you've got HIDs in OEM housing, and upgrade to projectors. Just buy new bulbs and you'll be good to go
