I am currently installing a 55w HID kit from DDM Tuning with a relay harness and I have a few questions.

For the connection to the stock harness, what is supposed to hold these prongs in place? The lights come on with no problem with them in place, however there is nothing holding them firmly into the stock harness?


See those male connections into the stock female harness^

The plastic housing that the lights came packaged in; is the rear of that housing supposed to come off? or just chill in the back of the installed bulb?

Rear housing would not fit over bulb for removal. Problem?^

I am also getting a buzzing noise from my ballasts when the lights are on. Is this normal?

I couldn't find any threads relating to my specific problems.
Thanks for any help guys, I'd like to get this figured out before night fall so I am not stuck indoors tonight.

 

Looks like your connecting straight into the car harness, not recommended, but with the proper connections (not supplied w/DDM) it can be done. What you really need is a heavy duty harness that connects to the battery, then one of the stock connectors is used to trigger to harness to supply voltage directly to the ballasts.

So http://www.ddmtuning.com/Products/HI...Wiring-Harness is not the correct harness? It connects to my battery and a ground. How would my stock connector be used to trigger this harness?

 

First thing I would do is cutoff the clear plastic piece, then remove the rubber bushing that only needed with sealed housings(not the TC) those 2 short wire toss to the side, take another look at the wiring then. You should have 2 HID bulbs with 2 AMP wires from each connected to the wire coming out of the ballasts. Then from your DDM harness connect direct into the ballasts (looks you have already done that) Then you should be left with one connection to go onto one of the stock connectors to trigger to harness.

The link you provided looks like a generic harness that might not have the proper connection to the stock H11 or 9005 low beam connector.

 

My bulbs have 2 wires that go from the bulb, through the resistor, and into the ballast.

My ddm harness is plugged into my ballasts.

My ddm harness has an additional (male) connector on each side, this connection fits into the (female) connection from those 2 wires you told me to discard. Those 2 wires have the metal prongs on them that fit loosely into the stock light harness.

The additional male connector from the ddm harness does not seem to fit with the stock harness.

Am I wiring incorrectly? or missing something that goes from the additional male connector on the ddm harness to the stock harness?



Photo for clarity.
Alright so the red and black wires coming from the bulb have 2 connectors that go through the resistor and into the ballast.
The ddm harness has been plugged into the ballast, farthest connection to the left.
The connector I am holding comes from the ddm harness, and plugs into that yellow coated female connection just hanging above the light. That yellow coated female connector is attached to a red wire and a black wire, which are pronged on the end.

 

Lose the second set of wires attached to the bulbs, this has nothing to do with your type of setup, those wires are for sealed housings with the factory harness connected internally within the headlight, they would jump out of the light to the trigger connection of the harness. Lose them quick and everything should become clear if you have the correct harness.

All in all you could hang the entire setup outside the car on the ground and only the trigger wire, battery+ and battery- would be attached to make it work.

 

So do I have the wrong harness, or do I just need to get the correct adapter from the ddm harness to the stock light harness?

 

DDM confirmed that I am missing an adapter that goes from their harness to the stock housing. They are sending me some free of charge. I will update when I receive them for anyone in the future who might have this question.

 

i just bought a set of HIDs from DDM, but since im doing a retrofit i bought some D2S bulbs and the same harness as Rawrtc,just wondering if im going to encounter the same problem? and if i am wat do i need to get?

 

this is how you're supposed to connect it...

battery--> relay harness
factory wiring --> relay harness
relay harness --> ballast
ballast --> bulbs.



if there are any loose connections, I just use a zip tie to loop around each base of the female and male connectors, and use a third zip tie to pull them together.

the buzzing noise is normal. this is not only with DDM ballasts, but with OEM ballasts such as Denso. Make sure you properly mount your ballasts (I wasn't sure if you were gonna just leave it on top of the battery). PM Me if you have any other issues.

 

Great post mrjtang !

So you really need to be concerned with the harness connection to the single factory headlight connector, the rest in industry standard connector for plug n play kits.

 

Yeah, I was just missing the adapter from the harness to the stock headlight harness, which is a 9006. The adapters should be on their way.

I noticed though that my right parking light stays on when my headlights are on, which is the side that is not connected. (As in the stock harness is electrical taped away) Why would that light be on?

And thanks for the clarification with the buzzing. And yes, my ballasts are firmly mounted now

 

parking lights are separate from the low beam lights.

 

So what might make it stay on while my low beams are on as well?

 

The city light in the low beam reflector and side marker light are on the same circuit and come on together.

 

I'm assuming city light = parking light?
My parking lights are just under my high beams, I have an 09 with projectors. So they SHOULD be on when my low beams are on? Either I have a light that is on that should not be, or I have a light that is out when it should not be.

 

ok, I have a 09' also, city lights are those little 194's in the high beam location and then come on with side marker or parking lights.

 

Okay. Well ever since installation of these lights my left city light and left side marker light do not work. Sometimes my right one doesn't work, sometimes it does.

 

So recently I was having an issue where both lights would suddenly turn off, then quickly back on. Both lights at the exact same time, no flickers, just turns straight off then immediately back on. Checked connects but everything seemed fine.
Last night they shut off and would not turn back on, drove with the brights all the way from Warped Tour in Pomona. They eventually came back on the drive home.

Checked my relay last night and this morning to see that my fuse inside is completely melted. I popped it open and tried to remove the fuse but it has become part of the relay now, and I did a search and found that this has happened before to other owners of the DDM Tuning relay. I tested with a volt meter and the relay seems to be getting a current even when the car is off?
Anyone know what would cause the relay to melt my fuse?
