OEM LED headlights conversion adapters for 14-20 halogen 4Runners!

A quick review on the FBC harness for quad high beams - excellent build quality and 100% perfect functionality. Would buy from again! My only recommendation would be that the wiring to the relay have additional slack. This would allow for better options for mounting.

 

Thanks. I forgot to mentioned that pic was taken before I lowered both the headlights and fog lights. Been driving almost 2 weeks now and haven't been flashed yet.

 

Lengths were picked by @mynameistory based on his specific choice of mounting location. Do others prefer longer as well? Curious myself but I’ve never installed one of these and I’m therefore flying blind on this topic.

 

My use case maybe different as I added a longer wire to the shutter wire to go inside the cab to an oem style switch. I'm happy with the length of the shutter wire.

 

I bought Bi-LEDs from a 2022 TRD Pro that are going into my 2017 so I will be purchasing the Quad High Beam harness; but I also purchased a set of Diode Dynamics Elite Series fog lights to install as well...

Which version of the FBC DD Backlight PNP harness do I need to order to avoid wiring going across the grill?

If I am understanding correctly I should order with the "Fog Lights (2 x 12")" option..

 

I don’t know of a good way to combine PWM DRL with parking lights for backlighting. I think a sidemarker T harness for just parking lights is the best choice?

Make sure to pick the DD SS3 option which is a pair.

I made something fancier for @mynameistory with relays so it flashes with turns but that was likely so ridiculous as to be not worthy of consideration.

 

Very silly and still working great by the way!

 

Let me know if you get to work drl bulbs for both drl and high beam functionality.

So far I absolutely love the wire daveesa sent me to trigger my auxiliary lights with shutter wire.

 

Some of the newer purchasers have asked for a clean/comprehensive install guide. If anyone is willing to do something like that, with photos, I will gladly link to it in the item description. Specifically the relay mounting location isn't super well documented so having some guidance on that might help everyone in the future.

 

Hopefully this isn't off topic, but can someone confirm that the 2014-2020 Halogen only and 2021 LED/Halogen Hybrid completely interchangeable just by swapping the connector on the housing?

So both of these statements are true just by swapping the connector?

A 2014-2020 4Runner can use the 2021 LED/Halogen Hybrid

A 2021 4Runner that came with the hybrid can use the 2014-2020 Halogen only

 

Attention all: I've just received news that Dave/FBC is no longer accepting orders for harnesses, and this is expected for an indefinite time. I do not have any other information.

Was looking into buying some last night n saw that
This really did just happen huh?
Sucks…not only do I need to improve the 4Runner but my moms ‘17 Highlander hybrid xle…still can’t figure if the newer oem led housings would fit hers kinda like we’re all trying to do

 

@mynameistory Mind getting me up to speed on these? I can build them (some of you may have ones I have built. Most likely if there is a forgotten piece of heat shrink…) but I have no idea which ones do what. I read your initial description which helped. @daveeasa offered different versions, so if I were to take these over, I’d really like to understand what does what. Do these descriptions match the harnesses?
This one uses a wire to trigger the relay and the 9005 stays connected.
This one I am guessing by process of elimination….

So last option is this one:

This one uses the trigger to break the circuit on the 9005.

Am I understanding this right?

 

I really wish Dave comes back with his products. Too bad I didn't have time to do a video yet, but I'm very happy with his product.

 

If Dave doesn’t come back on these, I will take over production probably.

I suppose I should introduce myself: I have worked with Dave for a while (years. Like 2 or 3 now?). Kind of a loose partner in FBC, mainly on the Tacoma side. You can find me under the same name on Tacomaworld (best place as I’m there the most often) and tundras.com. I have done some Tundra stuff as well. My experience with T4R is limited to building these and some early prototyping of a trailer wiring tap. But I did these blindly without knowing exactly what they did. So I am trying to get up to speed on that part here. I can make a test rig (Dave always did that part for them) easy enough as I know that voltage applied to X causes Y to happen, but I’d like to know how that works on the vehicle itself.
I am not certain yet if I’ll be taking these over. I do hope Dave will do some still, but I get why he wants to hang it up as well. So I’m just trying to get prepped and decide what I can do (mainly a question of volume as I am just one guy in his laundry room).

 

Johnny, you need a sample of the low beam only? I push hard to quad high beam instead but some guys want 100% stock behavior which is LED projector high beam only.

instead of a T like quad high beam, the 9005 + input goes to 30 and output from 87A. 87 still feeds the led projector shutter which is only active when low beams are on, same trigger for the relay.

Also different tubing, Kind of like a DIR mixed w the T4R conceptually.
I can send you a sample if you want. Same lengths.

 

The “no shutter” is a simple pass through adapter. 2 wires in, 2 out.

the two complicated ones differ functionally only in a single way. With low and high beam on (aka brights and not DRL) the led only harness does not have the 9005 bulb lit, while the quad high beam harness does.

 

Long time lurker, first time poster. My sister just got a 2020 4Runner ORP and her headlights were disappointingly dim compared to my 2024 4Runner Pro.
I upgraded bulbs with advice from this thread but the light output is underwhelming, so I bought a pair of take-off bi-LEDs for her.


I was going to grab @daveeasa 4way high beam harnesses and seems I just missed the boat so if @Puppypunter is building the 4-way harnesses I'd be interested in buying

I am electrically inclined and have built wiring harnesses for lots of other electronics, but not for Toyotas. In what little I could find online Toyota OEM connectors seem unreasonably expensive. How does one go about sourcing connectors to DIY a harness on Toyotas? @daveeasa what are your secrets

 

I think I've got it down from the pics. Looks like mil-spec blue from 9005 female to 87a, mil-spec green from 9005 male to 30? I just wasn't too sure as to which one did what. So these are designed to convert 2014-2020 to 2021 Pro headlights? One does it in such a way that you can use the 9005 as well as the LED for high beam, and the other follows stock behavior having the 9005 shut off when the high beam is activated?

If Dave is cool with it, I can build you a set. I'll shoot you a PM. As to where to get the parts, corsa-technic is a great starting place. They have a good majority of the ones you might need for Toyotas. The are US based, and great service. Most Toyota stuff will fall under Sumitomo TS090 or Yazaki 090II sealed series. The terminals for those two are the same. Corsa-technic cross references everything (I think everything at least) with a manufacturers part number, so if you are looking for a Toyota 90980-10942 connector, you can search that and it will take you to the right connector. Some other places that are good for non-Toyota based are mouser, digi-key, customconnectorkits, prowire USA (I can't recall their deutsch specific url, but prowire has all the links), and Waytek. The biggest pain with building these really is just sourcing everything. You might end up ordering from 4-5 places, paying $8-20+ (if you end up needing stuff from Japan, or Waytek can be high too) for shipping from each place. That is part of the value guys like Dave and I provide. In addition to owning the tools, we try to order in bulk. Dave much more than me. My true worth is understanding why SR Tacomas hyperflash so easy

 

I use 18 gauge rather than milspec on these. Solid green and green w yellow stripe. The green w yellow is DaveSpeak for “DRL with high beam” and solid green is “DRL only”. High beam only is yellow which feeds the shutter on the led prokector. All 18 gauge TXL except the relay coil gets 20 gauge white w red or black stripe.

 

The headache on parts is paying corsa prices on 2 each would add up to a hefty sum and then you still have to get relay connectors and relays somewhere. It makes more sense for Johnny or I to handle these. If J bomb wants it, I’ll make sure he has parts.

various reasons why I can’t do these this month at least.

 

That green and blue are TXL 18? Looked glossy, so I just assumed you over engineered it like crazy.

 

Blue is driver low beam positive. Red in passenger. Yellow for shutter. No milspec. All low current other than 9005 which might see some real juice. 16” run IIRC so I kept 18 but could use 16 TXL maybe if you wanted to be super confident on minimizing any potential losses. Could maybe try both and measure voltage but you’d need a T4R to test on and I don’t have one (yet).

 

@daveeasa @mynameistory
On the 2022(?) and newer, is the reason that you don’t drive the 9005 for high beam as well because the series wiring providing 6V?

 

You’re asking why no harness to convert 2022+ to quad high beams?

I have noodled on some design ideas. I don’t know if any 6V relay options as that would be cool, particularly 6V sealed / skirted. I don’t know of any higher wattage dimmers either. But it could be possible to go 12V DRL (I have a harness for that) then PWM dimmer for DRL and full bright for high beams. Just kind of a long harness there. Keeping 6v DRL and 12v high would be tricky with the wiring as it’s likely to short power and blow a fuse without a momentary delay between DRL and high.

 

@daveeasa Yeah.

 

Anything I can add as far as this topic?

 

I was thinking a relay triggered by the shutter wire (that is present on the 2022-2024, right?) that toggles between 6V and 12v being sent to the 9005. Wouldn’t be hard to do. Could add a diode to the 6V side if that’s a concern. The big question is where to get the 12V from? Could be a constant 12V, so the battery? Maybe a fuse tap, but I’m always weary of those for larger draws. Grabbing it from the shutter or the low beam are options on paper, but I don’t know what kind of wiring is present, and if it could handle the extra load. I think a 14g from the battery to relay on drivers side with an 18g going from that to passengers side would be plenty though. Not sure how much interest there would be for something like this though. You could do it all with a single relay if you really wanted to, but it would be a lot more wires running across the front of the truck, so I’d probably stick with the two relays and a single wire. I know I don’t have to apologize to Dave as he is used to my babble, but sorry to everyone else for not making a lot of sense….

 

I ain’t done with you yet!

 

Makes perfect sense why bulk is where it's at, nevermind the experience and practice that makes your harness a cut above DIY; fully appreciate the value folks doing this bring.
