Package received from Taiwan! - Page 3 - Toyota Yaris Forums

It gets even more complicated to wire up the Yaris so you can flash the high beams because of the way our cars our wired. The power is always on, even when the lights are switched off. The high and low beams are switched by way of the ground. Here's how I wired mine:

Unfortunately, the high beam indicator no longer works with this setup. I tried many different resistors to fool the car into thinking there was a low beam filament there but to no avail. I finally wired up an LED on my dash as a high beam indicator.

R1, R2 and R3 are relays.

$650 was a great price BTW. Good luck getting them working.

If I get it to work! haha

Wow, the 12v is on even with the car off? I didn't expect that... Sorry for not taking that into consideration, because that does change a few things...

Violin, instead of resistors, have you tried using a small bulb like a turn signal bulb? I would just find somewhere to tuck it away, or even use it to light up the engine bay =p

Not the car (ignition), the light switch.

Possible, although I've already drilled a hole in my dash for the LED, so I'm done.

taKuto · 08-04-2007, 03:17 AM

GabL, i'm sure the only difficulty you'll have is the wiring harness for the HID's. The schematic drawn up by Violin looks to be correct. Just build one of those and you're set.

Violin · 08-04-2007, 09:45 AM

If the thought of building a harness scares you, there are plenty of harness builders around. Just explain exactly what you need - that schematic would help a lot.

It would be cheap compared to what you've already invested. Check here for some: http://www.hidplanet.com/forums/viewtopic.php?t=20144

Just wanted to confirm, is the DRL in our current H4 bulb uses the high beam filament? If so, shouldn't the high beam wire and the DRL be the same with just different voltage supplied at different time? i.e. at DRL, a lower voltage is supplied, and at high beam, full 12V is supplied through the same wire? If this is the case, then I can just wire the high beam wire to the halogen bulb of the new HID unit using the same concept? Thanks in advance.

*Chris07LB* · 08-07-2007, 09:19 AM

The key word there is, in "our" headlights. Being as everything is seperate in your new kick ass one's, they may wire things differently right from the start.

I would look into Volins suggestion of someone making up a harness and figuring everything out for you. Might save you some stress in the long run.

taKuto · 08-07-2007, 11:38 AM

the DRL uses the low-beam for us. You can confirm this by turning on/off your headlights at night near a wall where you can see the change is just the brightness when the headlights are turned on.

i should add, this is for my echo, which should not be different from the yaris but it might. The same method to check still applies.

*Chris07LB* · 08-07-2007, 01:57 PM

Well I would think its a no brainer for it to be a lower voltage off the LOW beam, beacuse although its a lower voltage, the beam PATTERN would be aim'd up if using the HIGH beam portion of the H4?

Violin may be able to shed a little more light here..

GabL · 08-07-2007, 02:01 PM

I just checked the wire diagram for the Yaris, and it seems that taKuto is correct, the Yaris uses the Low Beam filament as DRL... which creates a bit of a problem. If I'm using the H4 common wire as the trigger for the HID, will this common wire be on when the car is supposed to be running on DRL? I can't seem to understand the diagram from Violin, as in the H4 plug, the H terminal is not linked to anywhere? GuySmily's diagram seems to be much simplier with just one relay?

*Chris07LB* · 08-07-2007, 02:13 PM

Well then, if you are expecting to keep the DRL box hooked up in your car, and splice off the regular plug to fire your HID's, it wont work. Keeping DRLs and having HID, will "strobe effect" your ballasts, and kill them over time.

Hence the reason for disconnecting the DRL box for anyone installing just a plug-n-play in their Yaris.

Violin · 08-08-2007, 08:27 AM

I don't really have a solution to your DRL dilemma. Would it be legal to have a separate pair of lights, perhaps behind the grill, that come on whenever the ignition is switched on? That would be simple.

In my diagram, the car side H4 plug plugs into a female H4 plug that I purchased and integrated into the harness. See my DIY for parts suppliers.

taKuto · 08-08-2007, 11:12 AM

You will only need one relay, and diodes for the low beam and high beam triggers which connect to the relay. You cannot use GuySmiley's harness since that's for positive trigger. You will need a negative triggered harness made. Wish I had the time to make you the schematic, but I'm sure you can find it somewhere.

What's the difference between positive and negative trigger? And I thought I only need the low beam wire as trigger, as the high beam wire I will plug directly to the hagelon light.

Black Yaris · 08-08-2007, 11:28 AM

dumb question.... but since we have city lights in the LB, could you just use those as you DRL? or can you hook up the high beam bulb on the same circute as the parking lights and use relays in a series to have them shut off when the lowbeam HID's come on..... only down fall to this will be no regular Highbeams at night
I can draw up a scamatic if you do not understand... but it will work, and you can keep your DRL disabled and run HID's :)
