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!

[@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?

[@RyanMiller3039]

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

[@redwingdetroit9671]

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

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

[@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?

[@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.

[@robward380]

Simplified and detailed ! Love the videos !!

[@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...

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. :)

Eduard Tomas Thanks for your comment!

[@chefvr6]

Can I also do the same process for the foglights as well?

[@Turquass]

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.

[@AiiRSTRiiKEOFFICIAL]

how do i know which relay and hid kit to use

[@tribulation138]

what do you do with the extra connections it comes with?

[@Inshallah42O]

Let em hang I guess? I'm trying to figure that out too

[@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.

[@jeffreysmith2364]

Awesome video, thanks, makes my install much easier/faster

Eric, I bought a relay harness for my light bar. The on/off button switch has a red light for off and a green light for on. When the ignition is off the red off light is lit up. Will this drain my battery? My guess is it's like an alarm led. Love your videos. Thanks for any input

What is the best hid kit to buy on the market?

[@JaneDoe-hi9bt]

What if the Xenon bulb cannister is cracked? It was delivered that way. Is it still good to use?

[@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.

[@DrLee65]

Where did you get the Relay portion of your kit mine didn't come with one

Don't be that guy and install hid's in a reflector housing. Be kind and not cheap and buy projectors. Your not the only one on the road.

[@seandonaldson4922]

Its not that bright without projector. Its not as bad as regular high beams.

[@JiMLiTtLe905]

it is that bad. any housing made for halogens cant have hids. that includes projectors that came factory with halogens

[@MCOB2019]

+JiMLiTtLe905 I hate to be that guy because i agree with you i hate those drivers, but in my case i kind of have to. I ordered some smoked headlights and the light output is kind of bad. The glare is also way less than the clear lenses so i feel like i wont be blinding people too bad.

[@abadran8174]

True partially. Do you know that there is cars that come with hid in reflector from factory? Probably you didnt. If the housing has the shield made for it it makes a very good cutoff actually

[@LittleJimmyNorton]

Make a Casper shield?

[@lmapes]

So you basically leave your other factory plug not being used to hang. Only use one for 12v from headlight? Thanks!

[@christopherfoucht834]

Are there any videos showing installation of hid kit for 2005 trailblazer? I see videos after install but none of the actual installation itself

[@JuanMColacion]

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.

[@lennycook206]

I bought A golf plus 2005. Its just failed its annual mot inspection as the law of these HIDs has changed here in the UK. To pass I need to remove the HID conversion back to the original. Any idea how to do this?

[@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!!

[@richardhartford609]

The relay protects the low voltage side of the circuit (which often runs under the dashboard) by closing a switch (internal to the relay) on the high current side should current get too high.

[@udayajayaseelanjayabal3262]

Ballest input Connector type?

[@IceColdJi]

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.

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**

Do i need to disconect the positive or just conect the red cable on top ?

[@mariocortez9698]

Good question

[@JunjiHori-s8w]

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.

[@dial2fast]

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

[@bboytosoldier1588]

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

[@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?

[@dial2fast]

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

[@1416vincent]

What size fuse did you use?

[@dial2fast]

10A fuse will work fine.

[@seungjoon2037]

Hi, thanks for the video. Recently I just change stock headlight(55w with 15amp fuse) to xenon Hid(55W with stock fuse 15amp), but the xenon manual says a 20amp fuse recommended. Do I really need to upgrade the fuse rate? Thank you.

[@abhijeetdeshmukh8818]

Nice and simple explaination. Thanks and subscribed, please provide the feedback, how is the operating temperature compared to halogens, i mean heat build up inside casing. I have heard hid are cooler than halogens. How is the long term performance?

[@dial2fast]

HID will last a very long time, but both HID and Halogen run very hot. Maybe one is cooler than the other, but again, both are very hot.

[@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.

Hopefully you or someone reading this can help me with the issue I have right now but basically I was trying to install the hid kit with relay on my car and the passenger side of my hid bulb won't turn on and I couldn't figure out why. It was also making so buzzing noises which supposedly I heard that it wouldn't happen with a relay kit. I don't know if it was due to the fact that the plug that was plugged into the bulb was left hanging, but I only have one signal wire which is connected to the driver side.

[@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

[@dial2fast]

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

[@americanmade422]

Doesn't the ground go to the ground terminal in the battery or does it matter? I used a ground that was on the side of my engine bay but other videos say to use the batterys ground. Not sure

[@dial2fast]

The car chassis is tied to battery ground. Check it with a multimeter before you connect it.

[@christiangomez9619]

What brand is this HID kit and did it come with the relay harness?? Also where did u get it and how much?? Thanks

[@dial2fast]

These are no name brands off eBay for about $26. These are DC ballasts and not as good as AC ballasts. The AC is much better. Relay harness do not come with it. You can find all the these on Ebay with many sellers selling them.

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.

+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.
