How To Install HID Light with Relay Wiring Harness

[@Mainbusfail]

9 years old and more relevant to me than the OEM white papers. Thank you

[@willchu]

This is the best HID kit installation with relay harness that I've seen on KZbin. Thanks bud!

[@RyanMiller3039]

I like that you laid everything out on the ground. It's much easier to look at.

[@danimalmx3]

TIP: For anyone with this kit or similar and is still having issues after wiring it like the video here is a fix. Plug the pins into the connector just as it shows in the video. When you plug the connector into the red part on the ballast just flip them around on both of them. Mine actually had a positive and a negative mark on each one to match them up. So you’ll want the positive side to go into negative slot and the negative side to go into the positive side if that makes sense. Many hours of frustration and this is what finally got mine to work correctly.

[@benshaw576]

No matter what I do to mine they remain dim, they start up really bright then within a second return to a dim state, does this mean my 12v current isn't strong enough?

[@redwingdetroit9671]

Tthis is the kinda vid the vendors shouldbe doing. Makes sense now thank you

[@robertgelley6454]

Excellent explanation! Concise and straight to the point on how to everything hooks up. Great description, especially when laid out.

[@90acurals]

Just curious why doesn't the passenger Factory harness get used only on the driver side wouldn't that cause a light bulb out warning on some of the newer luxury cars

[@Ikararua]

Awesome instructions....my surprise was when I saw the nissan badge...I got a 2011 max and the engine compartment is very similar. Saves me some time figuring out where to wire and how to route it.

[@miguelmora92]

very useful this video!!!, very accurate with the install using a harness here is a tip that im using on my accord 94, with the harness you have 1 vehicle connection free so what i did was to unify that connection to the high beam bcos im dont like to see any wiring hanging there also, to put into the high beam a capacitor just to have peace of mind, hope this tip like it and well greetings from colombia. :)

[@fletchforce]

Great video, I have a question about the extra wiring from the ballast. If I could put a picture on here I would show you. I have extra wiring for the factory wires. Do I just cut them out or what?

[@jbmjbm323]

Good video sir. People doing installs (plug & play installs) with just the factory stock wiring may end up ruining/overheating the wires cause of what you said...the ballast uses alot of current to start up. And that is why you used relay harness because it uses the right awg. gauge wire for the ballast and it gives it the amount of power it needs to work.

[@galodoidousarenato5504]

Hi Sir, Can you tell me if the kit works without the relay harness? because the one I bought on Amazon doesn't have a harness

[@jbmjbm323]

@@galodoidousarenato5504 it should still work. My only opinion though when you connect it direct to the headlight plug, the stock wiring for the bulb may overheat and burn out the wire if the stock fuse does not blow because HID startup uses alot of volts/amperage it says on the ballast. I use a relay for my hid lights because I can hook up a bigger gauge wire to run my hids. The headlight plug runs to a relay, then the relay would switch on and send power from the other wire I use to power my hids. You should check out videos on youtube on how automotive relays work. But without a relay, your hid kit should still work. Just read the instructions...

Hi. Thank you it was very clear nice expression. I have a question. I bought a osram hid kit(new). I tried it by my passat without relay. But it flickers 2 sec. and stops the working. (Both of xenons) I have to make relay connection to fix this problem? right?

[@dial2fast]

Assuming the new HID kit works fine, if you install a relay wiring harness for the HID, then you will be powering the HID directly off the car battery and that should take care of any flickering or turn on issue.

[@ahmedahmed-ul7gr]

Where do you but the relay from

[@Ruhvenge2]

when connecting the wire to the positive terminal am I in any danger of getting shocked or electrocuted, or do i have to disconnect negative first just being safe thank you

[@dial2fast]

The 12V DC will not shock you. You don't need to disconnect the negative terminal.

Where do you buy a replacement for this unit when the bulb breaks. I purchased my Mercedes with the headlights already upgraded an I have no idea where to go to get a replacement bulb.

if my car has different bulbs for high and low beams, does that mean I need to run two sets of this wire set up for each set of bulbs? also can you confirm that this type of installation with a relay will prevent the computer from being compromised?

[@peterleprich1352]

Hey I'm wondering the same thing! My dodge chsrger has a high beam bulb an a low beam bulb for each side... does thst mean I have to run the lows with 2 ballasts an a relay harness and 2 more ballasts an a relay harness for the highbeams??? **Enlighten me Please**

You can get a universal relay harness for cheap. Take a look at this one amzn.to/3eJMNeY

[@asharma5958]

When your hooking up your harness to the nut on your battery you dont need to dissconnect the battery right? I dont want to lose any of my settings in my car? Thanks and great videos!!!

[@dial2fast]

A Sharma You don't need to disconnect the battery when connecting but just make sure you don't short anything while connecting.

[@Grizzleback07]

You can also remove the fuse from the power cable on the harness. This way no power is flowing to the relay switch and allows you to secure all wiring connections prior to activating the lights.

[@dianagraham4021]

So it has to be wired to the battery? My stupid Prius has the battery under the back seat..

[@dial2fast]

If you are using a relay wiring harness, it needs to connect to the battery.

[@TheDave5619]

I have a hids for my low beam and they work great. But I tried putting hids on the high beams and don't seem to turn on do I need a relay to start up? Thanks in advance for the help

[@dial2fast]

HID are not ideal for high beam as the warm up time takes too long for real practical use. There are lots of LED lights that performs very well. You should look into those. Also easy install as they are plug and play.

[@TheDave5619]

dial2fast thank you!!

[@corbind.9395]

Out of curiosity and before I get a headache looking at mine (came with absolutely no instructions) on your passenger side, did you still have a male plug that connected to nothing?

[@dial2fast]

With the relay harness that you install for the HID, you only need to connect one side of the headlight connector as that is used as a trigger to turn on the relay. The other headlight connector is not used.

i recently added a relay to my HID set up. I noticed that the wire from the battery to relay gets very hot. Is that normal? It seems dangerous to me that it get hot. Any responses would be appreciated.

If the wire is getting hot, then the wire is too thin. Use a thicker gauge wire like 12-14 gauge.

dial2fast so you leave the far-side connection to the car just plugged into nothing? I used your video for my install and everything is working great, but I’m getting a message inside saying a bulb is out because that connector isn’t hooked up to anything.

[@bloo22ca]

Are these for low beam or high beam? Also my car has a projector headlight. Would they cause lots of glare for that kind of headlight?

It's for low beam. These days, you should really look for LED light. Fast startup, pure white color, easy install.

[@rogersikorski3794]

Great video 👍👍 thanks

[@jbmjbm323]

Saw a post here, someone had both hi/low beams on the factory plug and they wanted to install both but this video was for low beams only. I would think if they wanted hi and low beams, they would need to buy a bi-hid kit for both hi/low beam and for the relay harness it may look alittle different I think, but basically the same thing here in your vid.

[@yessir843]

quick question, what the hell is that connector between positive and relay, a fuse? Also, I see that one headlight connector plugs into the relay harness does that mean the other one is inactive/laying around because the one already sends the signal so the second is rendered useless?

[@amozonkany]

Yes it is a fuse. Yes one headlight connector plugs into the relay harness (normally the side closest to the battery) the other one is left unplugged, since it just sends signal from factory harness to relay so you just need to connect one side.

[@eyyyyyyman]

so im ordering aftermarket headlights for my 2002 530i due to a deer hitting and cracking my passenger headlight and the aftermarket I ordered says non compatible with factory HID cars which mine is. Will I be able to make it work?

[@myexperience9177]

Yes by installing a different kit. For example i ordered aftermarket headlights also for my car and came with an LED strip inside (which i think it looks cool) but my original HID bulbs did not fit so i had to buy a different set that would fit my aftermarket and it worked.

[@janut416]

I have installed x5 can-bus ballast with 35w HID bulb. It is working good only as a head light but i lost my DRL (Day running lights). Will HID works as both head lights and DRL?

[@dial2fast]

+Sutha Tharakan HID is too bright for use as DRL. You can of course install it, but its annoying to oncoming traffic.

[@janut416]

+dial2fast one of my friend told me he is using HID as DRl as well as the same HID working as his head light. ( dim light + head light in one HID) thats what i'm confused. Mine is just as head light. When i start the car no lights will work. But in canada its a law to use a DRl in vehicles. I can install an external DRL but I'm confused how his HID working as both DRl and headlight. My HID was flickered when low voltage is supply, so they changed the ballast and installed x5 can-bus with flicker canceller.

[@dial2fast]

+Sutha Tharakan Factory DRL from years ago (non LED) operates by cutting the voltage in half. So it puts 6v on each high beam bulb. That's why it's not full brightness. I am not aware of any ballast that operates at both 6v and 12v. You might want to take a look at your friends car and see what's his setup.

[@janut416]

+dial2fast yes. I'll go and see his setup this week and will share with you what he did for his DRL. Thanks for your replies.

[@dh123ize]

So did it work when you bought a relay harness

[@singapore401]

Hey I’m using HID lights with 55W ballast for my fog light and the fuse keeps on blowing. From my understanding is the during startup the HID draws a high current and will drop back down. So due to the high draw of current it blows my fuse. Therefore in order to rectify this, do you think by using a relay harness with its own fuse that is connected to the battery then to the HID with its 55W ballets will resolve this issue? Thank you.

[@dial2fast]

I am assuming you are referring to the factory headlight fuse blowing. If that is the case, then you should install a relay harness to provide adequate current for the HID ballast.

[@singapore401]

Yes I meant the factory fuse keeps on blowing. Will be install a relay harness. Thank you for your help, greatly appreciated 🙏🏿.

[@dial2fast]

You will need a multimeter to check all the connections on the relay and power to the ballast. There is no easy way of figuring these things out.

[@freakychannel123]

dial2fast Hey! Was about to install hid lights on my car, but was confused about the two wires of the bulb. Are those two other wires (besides the two you connect to the ballast) that comes along with the bulb useless? If you use relay harness that is...

[@profdleeucc]

+Armyboy Check your connections; there are basically five connections; the red connection going from auto positive terminal to relay harness(this also has the inline fuse) @ one minute 22 seconds in presentation; the connection going from Hid relay wire harness to the factory oem original light socket harness @ one minute 27 seconds in presentation; the connection going from Hid relay wire harness to both the Hid ballast to power it and also its ground connection to chassis ground; the connection going from Hid relay wire harness to the other Hid ballast unit to power it and also its accompanying ground connection to chassis ground; then all one has to do is connect ones left/right Hid bulb to the pair Hid amp style connectors to power each Hid light bulbs respectively.

[@SimplySanju1]

I was following the same setup in my Hyundai Venue. But if I connect the battery line then I get a warning in console saying check headlight. If I give the headlamp line directly to relay and then connect relay to ballast, warning does not come. But I now face a new issue, the cut off line seems to be disappeared and the high beam from both lights goes to some top right in a wierd shape, no clue what's going on.

[@bboytosoldier1588]

I installed my relay and one headlight isn’t turning on do you suspect what the issue can be

[@djgenius10]

So you are using only 1 OEM headlight plug to give a signal to harness relay. The other OEM plug is unused, so you should get an error on the dash that the bulb is gone (from the side the OEM plug is unused). Isn't that right? Or does it throw an error on both sides, because the relay isn't drawing enough amperes from OEM plug and ECU thinks bulbs are gone?

[@dial2fast]

The trigger to the relay is coming from one headlight only. Most Japanese and US cars don't give any headlight errors. I think BMW and Mercedes will. If your car does, then you can try connecting the ballast to the headlight plug (plug and play install) without using the relay. Otherwise, check on the net to see how others are doing it.

[@djgenius10]

dial2fast Yeah, I am using it on BMW X5 2008 model. I used plug and play, getting power straight from both of OEM plugs, but xenons sometimes flicker/flash and one or another switches off randomly. I thought I would overcome this problem by introducing the relay harness, but this will cause another problem. Thanks for a reply.

[@jbmjbm323]

+djgenius10 You will probably need a heavy duty resistor/capacitor connected parallel with the headlight connection to the relay. This should simulate that halogen bulb is connected and it may be okay. I never done this so I don't know if this will work. Try at your own risk.

I have two 10 inch JL audio subwoofers ran by a 1000 watt monoblock JL amp in my truck and whenever I have the bass turned up my head lights flicker and I believe it's because I lack a capacitor between the 4 gauge connection from the battery to the amp.

Will instilling this fix the problem of my headlights flickering?

[@dial2fast]

+Nick Klink Headlight flicker is because your amp is drawing a lot of current when you have the stereo cranked. Using a relay kit for your lights will not fix the flicker. Also you don't have to use a relay for the lights if the factory harness provide enough current.

[@thebiggerman6975]

Im a little worried that if a short or ballast goes bad and the fuse blows you are left with no headlights thinking I may put a breaker in place of the fuse

A ballast going bad will not blow the fuse. If the fuse pop, it's because there is a short with the wiring.

[@thebiggerman6975]

@dial2fast well that's your opinion, when something electrical goes bad there's always a chance of a blown fuse and thus the loss of your headlights, that's why fuses are utilized if a ballast melts then that would be a short circuit , thanks for your input

How would we connect the HID Lows and HID Fogs both with wiring harnesses to the battery? Can we overlap them on the terminals? thank you

[@dial2fast]

+Vinayak Riyat Yes, overlap the 2 ring terminals.

[@vr4923]

Hmm. Okay, Last time I did that, for some reason it drained my battery on my car and I had to take my car to the dealer and they said the positive terminal was loose. I am not sure if that's what caused the drainage in my battery or not, but I am a little uneasy as to hooking up my harness for both my sets of lights again, as the issue last time left me stranded on the side of the road. =/

If both hid light do not turn on and you switch its polarity and only one turns on then the only reason they'll have you buy a harness is to bypass their mistake. Just switch the pins in the connector that connects to the ballast. Both should work without switching polarity.

[@JoaquinSanchez-db9gk]

is there 1 connection on the ballast that wont need to be connected? i cant figure out where it goes, i left it alone (disconnected) and still work

[@gameboy1984]

Joaquin Sanchez there's nothing left unplugged the only wires on the ballast should be the wires going into it for power and the wires going out of it to the bulb

Ballest input Connector type?

[@louaranda5631]

where do i find the factory headlight connector that would fit my hid's connector? I cant find it on my car.

[@dial2fast]

+Fernando Ramos That connector is connected to your factory headlight bulb.

Those HID bulbs look like D2S's. Shouldn't you be using D2R's to for your application?

[@LuisVega-so3tt]

Not sure if you'll ever see this, im using d2s, I want to replace my harness cuz I'm having all kinds off issues, do I need to look for a specific harness?
