I have been searching this forum high and low. Working my way through the 3000+ post lighting thread and I have been unable to find instructions on how to retrofit V6 headlights in an I4.

I am 99% sure the HI & Low Beam and turn signal are the same. And I know I can just pull the fuse to disable the OEM high beam DRL. So I just need the plug that connects to the LED strip and wire it to a switched power source and I need to know what wire gets the power and how the LEDs are signaled to dim when the headlights are on.

I found the part number for the plug --> 04321-S0X-305

Does it have wires coming out of it? What wire gets what voltage?

He charges $100 for what looks to be a $5 plug.
and we charge $101.00 to give you the answer. This has been beaten a tons of times on this forum. If you can't find the answer just go with the haгdtσp harness.

BTW...make me a $5.00 harness if you can

Just FYI, the haгdtσp harness does not work for the V6 to I4..only the Touring headlamp to I4. For some reason the harness he sold would not supply enough power to make the lowbeam of the V6 headlight operate. Another forum member and myself are trying to come up with a solution.

Look, dude we know it's unfortunate. We know he probably uses $5 in parts to build you the $100 harness. Whatever. You're not paying for the parts, you're paying for the service. You're paying to have someone who knows how to build a harness take time from his busy schedule to build you one.

It ****s, I know. Don't want to spend the money? Build your own harness. Don't know how, can't find instructions? Pay someone $100 to build it for you. After buying the $1,200 Touring headlights for my 30K car, $100 is a drop in the bucket in my opinion.

EDIT: Actually, 1KDH is right. Apparently it's even harder to build a harness for the H11 Halogen V6 headlights. So beware even if you decide to buy from haгdtσp.com. Sorry dude.

The V6 or Touring lights on an I4 requires some sort of relay the reason HTG's harness works perfectly for LED lowbeams and not for the V6 low beams because in his harness the lowbeam powers the electromagnet in the relay so some power is lost on the way out of the relay and halogen and HID bulbs require all the power while the LED low beams do not. If you already have HID's install a HID relay kit to fix that issue. Here is the diagram to build your own harness. http://haгdtσpguy.com/store/image.php?type=P&id=1115

So wait all u need is that harness to get it to work without cutting and tapping into the wires
You would still need to tap into the low beam to give the LED strip the signal to dim while headlights are on and run a power source that is switched with the ignition to power the LED strip but nobody is willing to share information on how to do that. I don't want to spend a bunch of money on headlights then fry them trying to figure out which wire is supposed to get power.

It looks like the relay is necessary to change the signal from dim high beams as DRL to LED strip as DRL. I wanted to avoid this by hooking up the LED strip directly to their own power source. That diagram (and all the other info I have found while searching) doesn't show what color wire is power/ground and how the LED strip gets it's signal to dim.

Even if I did want to spend $100 for $5 worth of parts it looks like the HTG harness doesn't work properly with the v6 lights and might be unavailable anyway.

I am ordering a few parts and I am going to order what I believe is the right plug for the headlights. Hopefully looking at it will give me a clue on how to hook it up. I have already spent way to much time trying to figure this out, I may just end up going with the EXLed strip mod. I wanted to get this done before it got to cold to work on the car outside.

I have the HTG harness for the 4cyl and it's perfect. I can tell you that there are way more than $3-4 worth of parts in the harness. I bought 2 sockets and a bag of 5 male plugs for $20+ that still needed to be wired when I was looking at converting that pathetic brown aux strip to a DRL. I scrapped that idea when I decided on the LED Touring lights.

The link did not show exactly what you get for $3.52 but there is no way you can get all of the hardware for both sides for that kind of coin. That does not include the relay for both sides. I'll stipulate that I may have gotten robbed but that harness can not be constructed for a few dollars. There are easily $30-$40+ in there at retail.

Correct. Don't do it, the harness makes it plug N play, tap nothing.

You would still need to tap into the low beam to give the LED strip the signal to dim while headlights are on and run a power source that is switched with the ignition to power the LED strip but nobody is willing to share information on how to do that.

Tap Nothing. Try to contact HTG and see what you need/advice. He is at Rick Case Honda in Cleveland.

I am with you, don't risk screwing something up and avoid tappping into any wires.

The reason nobody is willing to share that info is because you are the first to do this with a V6 that already has LED DRLs.

AFAIK, nobody has done what you are doing.

Some have skills building a harness, but those few also have the 4cyl.

OK. Some cornfusion needs to be cleared up.

You have an EX Sedan with a dual exhaust so you must have the V6.
Your thread title confirms V6

You talk about pulling the fuse for the high beam DRL.
You do not have a high beam DRL if you have a V6 sedan.
You have an LED DRL which is the LED strip.
Your high beam is just the high beam.
Pulling the DRL fuse will just cut your beautiful LED DRL strip and be counterproductive.

The only models that get the LED DRL are the Touring, Sedan V6, and Coupe V6.

All other models get the pathetic yellow T10 aux strip (in place of the LED DRL) and brown de powered high beam DRLs.

Would be a good idea to add V6 to your signature. I just added 4cyl to mine :thmsup:.

I have the I4 ex with the pathetic strip light, I added on the OEM dual exhaust. I want to upgrade to V6 headlights to get the LED strip. It seems like I should be able to reuse the OEM high/low/turn signal plugs, then buy a plug that goes onto the LED strip and run power ground and 'signal to dim'. I can't imagine this plug costing very much.

Again - To me it looks like the HTG harness needs the relay to direct the signal for the depowered high beam DRL to the LED DRL. By wiring the LED DRL up to a switched power source I don't see why a simple connector wouldn't work.

Didn't see that one coming, I4 with factory duals.

Still, no one has done what you are contemplating. This is a new area. TMK, all factory headlight conversions have been to the Touring LED that includes the LED DRL. I see no reason why the V6 with LED DRL would be any different than the Touring since all of the plugs are the same. You should be able to construct (easier said than done) or buy the necessary harness and PnP like the Touring conversion people like me.

About a year ago there was a ton of discussion about eliminating the brown high beam DRL and using LED bulbs in the brown strip and converting it to a DRL by running it off of a fuse tap either under the hood or interior box. I bought the tap fuses and plugs to do just that but made the leap to the LED Touring. I know that there were a few who did that IIRC glen e and one or 2 others at least. I think that is what you are looking to do. If so, your LED DRL will always be the same intensity (some are looking to do that with the Touring DRLs) and they won't dim correctly when you turn your lights on with a dirct tap and no relay.

Note: The factory LED DRL is only activated when the ebrake is released so if you are checking the function and the hand brake is up, the DRL will be off.

His price for the harness is actually reasonable. His service is not.

If I made the harness (I made my own for my Touring LED lights), I would charge twice what he is charging and even thrice for "options".

Agreed, I don't know where these people are coming up with a few dollars for parts.

If you buy the lights from him, he only charges $30 for the harness which is a steal. IIRC his lights were about $30 more than Majestic. Too bad HTG has damaged his reputation here with poor service.

Wow I'm glad I read this. I have an EXL V6 and want to upgrade to the touring LEDs. Good thing I didnt buy the harness. I just contacted HTG. Hopefully he will have an answer.

I can't imagine how a couple of plugs can be more than $20.

I love the look of the OEM LED strip but the $580 for the headlights is already pushing the limits of what it is worth to me. Adding $100 for a harness that I may or may not get and may or may not work just pushes this over the top for me. I didn't see the V6 headlights on HTG's website anyway.

I ordered what I think are the correct plugs and they are just plastic plugs without wires. Putting wires into the plugs is not something I know how to do, and at this point I don't want to invest anymore time trying to figure out how to do it. I am throwing in the towel on this one, I am going to go with the EXLED strip mod - I just have to decide which one.
