Were you able to solve your LED issue?

I turn the parking lights on and the High LEDs come on. I turn the low beams or the high beams on and the DRLs go to LED low. Do you think if I change the low and high LED wires it would correct this? I'd like the DRL LED highs on with no parking or HID lights on and DRL LED lows with parking, low and high beams. Thanks again Moto

It's not an issue as much as it just being a difference of FRS and GT86's body control module. The reason LED high comes on during parking lamp and in gear is that the DRL line on the FRS is shared in trigger as the high beam. (Remember? High beam bulbs are used by the DRL for Scion FRS... So whenever the DRL circuit is triggered, the LED will be in bright mode.) Parking lamp on or off, AND in gear, engine on, will illuminate High LED, but not with headlights on or engine off/out of gear. The LED pins can be reversed if you'd like the High LED on with headlamp... And LoW during DRL, can't have it in between as that's how the FRS's brain tells the lamp circuits.


Only way to really fix that would be to run a separate relay system to trigger and switch these light the way you want it. Only that part is what is different though, and a result we can live with and not be illegal either.

Having it wired with low LED on DRL has this neat effect on the FRS as BCU triggers the flash line for an instant, where the HID high beam flashes with pull of the flash lever, followed by the LED high strobing once as HID goes off...
Repeated flashing sort of blinks the high beam and LED alternately...
This being a completely safe side-effect of having it pinned to the FRS BCU this way.

I've tried the low and high LED wire lights both ways. I prefer the way Moto-P listed in his first post. The only problem I've came across is that with "ALL" the lights off (Parking, low and high beams) the High LED DRLs are not as bright as when you turn the parking lights on. They look a little brighter than the low LED's but not by much. Compared to Audi or Lexus LED DRL's running in daylight hours they look dimmer. Not sure why this is happening. So the way mine are working are as follows...car running, no lights on and brake off LED DRLs are medium bright, parking lights on they're really bright and then with low or high beams on they're at they're dimmest.

There's no setting as you describe of Medium Bright. The LED only glows at high or low. Depending on the pins fed.

I keep saying again and again, the issue with DRL and the quirks of duties on pins is a limitation of using it on the FRS, as the line switch for the high beam is on the same loop as the DRL on the USA cars. This we cannot change unless you want to completely rewire a separate relay system without using any of the original DRL triggers. But this is a nightmare as well since DRL is actually very conditional to many system triggers...IF you want it to operate EXACTLY like the FRS's original DRL.

Yes, and the LHD unit I have is indeed USA Legal as it was always from the start, as it was made with equipping it on USA cars until it was rejected by Scion's product planners.

On a separate note:
It is not unsafe even if it was not DOT approved, if it was approved in Europe or Japan... DOT is merely a USA entity of the government that regulates and restricts guidelines of how vehicles are to be equipped for each model year. But ultimately, the safety of any equipment rests in the proper installation, care, and use by the owner.
And, the design and workmanship of components being used... In this case, a Genuine Factory Toyota Subaru Part.
I feel that safety in this respect has little to do with legality, as DOT can be pretty arbitrary at times. Like I don't trust some of those DOT approved helmets for bikes... And always follow guidelines by FIA or SNELL instead...

I have good and bad news.

Good News: the FRS Release Series (Limited Edition) will come with these LED/HID lamp systems in the USA. Trust me... I'm the same guy that told you all a RWD coupe is coming to you back in 2006.

Bad News: FRS RS has no scheduled date of production at this time or launch date... So most likely as 2015 model in 2014... Is what I am guessing...
That's a lot of missed events and track days... Lol!

I don't think it will be that long...

Easiest and the most reliable way to wire the Japanese HID/LED lamps to Scion FRS halogen systems is to pull the pins out of both light assemblies and re-pin them into the proper socket location on the FRS lamp assembly connector. That way all connections are water-proof and original FRS sockets can be used without cutting most of them or tapping them at all, except one pin...
One can easily find another single pin male/female connector for this... I used the aftermarket HID bulb 1 pin waterproof socket as it is commonly available.
To remove the socket pins, you need to simply yank on the white plastic guide-locks to remove it, then finding the pin lock tabs for each one, move it up and pull gently on the wires from the back of the socket.


Japanese HID/LED (GT-Limited) "socket" pins:
#'s correspond to pin position in the 8 pin socket.

1. Not Used (Empty)

2. White - LED High (DRL 3.3W mode, 12V+ *must bypass the resistor on USA FRS to power this)
3. Green - LED Low (12V+ 0.5 w mode)
4. Black 12 Guage - LED Common GND

5. Red (12guage) - HID Ballast 12V +
6. Black (12 guage) - HID Ballast GND

7. Yellow - High Beam bulb position actuator 12+
8. Blue - High Beam bulb position actuator GND

On the USA Scion FRS 6 of the 7 necessary wires are all in the 6 pin socket, and it's a matter of re-pinning the sockets to proper locations. All of them except the pin needed for the DRL (LED-High 3.3w mode) are there.

To wire the DRL properly, pull the DRL resistor located on the right front bumper just below the horn assembly. Tap into the live 12V side of the harness and leave the resistor unplugged so it does not feed the high beam actuator in the Japanese assembly.

This is done because the USA FRS has the high beam bulb doing tha dual role of DRL and HIGH Beam, and Japanese assembly has LED High mode at 3.3 doing the DRL, and is separate from the actual HIGH beam which is done with HID main bulb with bulb position locator shifting the Low beam to high.

Take the live side tapped wire to the LED high 12V wire on the Japanese headlight assembly so you get full 12V, and at the same time leave the socket off the resistor so it does not feed the High Beam actuator with attenuated voltage that normally powers the FRS high side halogen... (yes I said this twice to remind you)...

On the Japanese headlamp, now you should have 6 wires left, after you connected the white to the DRL 12V circuit (with resistor bypassed)

**I'd just simply remove this resistor altogether as you don't want a shop or dealer plugging it back in. The FRS only needs it so it can under-drive a halogen lamp on high beam at lower voltage during DRL. The Japanese system does not use it, as it has a LED array that is designed for this, separate from the HID high beam.

Now you need to use this USA Scion FRS headlight "Harness side" custom socket diagram to put the pins in the right locations for the FRS socket to be used on the Japanese LED lamp to power the system correctly.

USA Scion FRS lamp assembly socket pin (6 Pin connector)

1. Green (High beam) 12V ----> Blue bulb position actuator 12V+
4. White (High beam) GND ---> Yellow bulb position actuator GND

3. Red - (Low beam) 12V------> Red HID Ballast 12V
2. Black - (low beam) GND-----> Black HID ballast GND

5. unused on FRS headlight but pre-wired on the car (parking GND)--------> 16guage Black LED Common GND
6. unused on FRS headlight but pre-wired on the car (parking 12V)--------->Green LED Low 0.5w mode 12V+

*7 not on the headlight socket, wired separately from the live side of the DRL resistor on the FRS DRL line. ------>White (LED High 3.3w mode 12V for DRL)
* leave the resistor disconnected.


Now you should be done.

Check Operation:

Parking lamp on = Low LED light up.
Headlight on = HID Low beam + Low LED light up.
High beam = HID Low and HIGH should now be lit with bulb relocated by actuator into the proper position inside the projector+ LOW LED lit.
Flasher = HID should power with actuator in high beam mode, and upon releasing the High mode LED also flashes for a split second (latter if the headlight is on)
DRL with all light switches in Off and with car in Reverse or Drive Gears, and parking brake down, engine on = DRL mode LED should be lit with full 5.5w really bright.

There you have it. Properly working like a Japanese GT-Limited 86.

Thanks for this.

Quick question - the white & green connections for High and Low, I'm assuming output is switched between them, in other words, they're never both powered at the same time?

Our cars came standard with the LED lights but they only work when the lights are switched on so I want to rewire them to make them work as DRL.

Funny enough, we've got an empty relay socket for DRL but fitting a relay does nothing.

Here is what I had in mind:


And here is the connector:



The colours seem different though?

That's all good news for me actually, gives me time to save up!

Hey guys, I finally sat down to do this after getting my lights in tuesday. I seem to have everything pinned correctly and the light functions as it should, however, I have a high squealing noise when I actually switch the lights on.

The lights come on and function as they should, and they flip from High to Low with no issues, however as long as they are on the squeal persists.

Any ides?

Are you referring to the "squeal" coming from the ballasts? Hid ballasts tend to make a buzzing/squealing sound as they power up the bulbs. It's completely normal.

Excellent, thank you very much for that information. This is my first vehicle with Hid's and ballasts so that sound was new to me.

In that case, I have everything in wired correctly. Thanks for the help every one, especially @Moto-P for his plethora of information he provided. I will get pics up tomorrow!
