Default HID install problems on 04 WRX

Hey guys and girls. Having some trouble installing an HID kit. It's an off-brand ebay winner. From the install websites I've seen from other HID kits, it's pretty much the same thing though. Got a cable coming out of the regulator (box) that connects two wires (I assume ground/power) to the bulb, then another cable coming out of the regulator which shoots to a red (power) and black (ground) wire. The instructions say to put the red power wire into the connection where the regular halogen bulb would go (flat rectangle clip), then ground the black wire. Problem is, it's not lighting up. Per the suggestion of another thread I found here, I've tried reversing the connector going into the regulator to swap the power/ground wire, no go. I've connected the power/ground wires directly to the battery and the bulb lights up, so I know that part of it works. Any ideas?

Note of interest is that if I have a regular halogen bulb hooked into the power coming off the car it does not light up until the metal bracket is touching the metal housing of the headlight (where you put the bulb into the headlight housing and secure it with the little metal clip. If I have the bulb out in the open it does not light up with the lights on. Keep in mind I've only tried this on the passenger side, as the testing I wanted to do required the battery to be active for the car.

Any input would be wonderful. Thanks!

First, disengage your DRLs.

Second, use a meter to find your positive and negative from your headlight harness instead of guessing.

Profile updated! Thanks for the info. I've read quite a bit of that, I'll finish reading and see if there is anything relevant to the problem I'm having. Good info there none-the-less.

I had read about the DRL relay, but after reading through I was not sure if that was a factor. I'll be removing the plug this weekend and post the results. Thanks everyone for the suggestions.

The DRL is a factor because it puts resistance in the ground lead. This is why when you ground your HID ballast, it finds a better ground path. However, the problem with this is that electrically, it is not ideal.

Your alternative is to only take the positive side from your headlight harness and ground the ground input lead independant of the harness. But this will most likely result in your HIDs being on all the time when the handbrake is down.

if you bought it off ebay try switching the pos+ and neg+ red and black, it makes your brain hurt but Europeans use positive ground, then disable your drlz.

did you all retrofit projectors in your 04's, or are you just running the HIDs through the stock reflectors?

I did run a test with a low voltage circuit meter and the ground I'm using completes the circuit. Just to double check I also tried last night to run the ground directly from the neg. terminal on the battery and that didn't help (just to be absolutely sure it was grounded).

The "harness" I'm using is simply the power plug that the halogen bulb normally plugs into. The negative ground is on a little clip above the headlight insert, so it appears the alternative doesn't work so well for me.

The hookup should be fine, since they do in fact turn on when hooked up directly to the pos. and neg. terminals on the battery.

Stock reflectors. I know.. I know.. I read the thread posted above and am apparently going to rot in purgatory for putting HID's in a non-HID housing. Too little too late at this point.

On a side note, I did read quite a few posts that even with the DRL hooked up the HID's should come on, but normally flicker and then go out. Mine don't even blink at me. But.. I still plan on unhooking the DRL and go from there.

Exactly which modern day Euro car uses a positive ground that you know of?

Stock reflectors are fine as long as you adjust the levels.....

Well, I unplugged the DRL this afternoon, still no lights. I'm leery of switching pos. and ground since I hook it up to the battery and it lights up, plus switching the polarities can't be good for the bulb.

I appreciate all the ideas guys, please keep them coming. I'm flat out of ideas here.

If that doesnt work them im out of ideas as well. I bet the ground isnt good enough..

Doesnt make sense that when you hook it up to the battery it works, and then doesnt when you hook it up to those wires.

If you want a plug and play harness system (which you should be using anyways) let me know, it will definitely work

Indeed, I even grounded it to the battery and still nothing.

If you can get me a harness, PM me with how much for each side. I'm up for anything at this point.

Wow. Anger management anyone? My point is, when I have it hooked up the same way it is, how is it going to be backwards if when hooking it up to the battery it works? If they were backwards, why would it work on the battery? I already explained this. But sure, I'll switch the plug end and report tonight. Christ man, take a vicodin and relax a little.

You have verified with a meter that the positive connection is in fact going to a positive power source right?

I had the same problem when installing HIDs in my '05. The headlights have switched grounds (-) and constant (+) with the ignition on. The red wire inside the headlight (that attaches to the stock H1) is the switched ground. The black wire (attached to the headlight reflector) is the constant (+).

Your HID ballasts should have reverse polarity protection built in... I hooked mine up backwards at first also.
