Hey,

Got bored today so decided to install some LED strips into the Yaris just above the footwell. So when you unlock or open your doors it will light up.
Its a nice feature when your dome lights aren't bright enough.

A few items you will need:
wire
fuse holder + 10amp fuse
4 pin relay
4 spade connectors
ring terminal
LEDs or LED strips (EBAY is the cheapest)

wire strippers
crimper
soldering iron
solder
electrical tape

A diagram of which wires to connect to. YARIS ONLY (COROLLA MAY BE THE SAME PLUG)



I did not take photos of what i actually did.

Where the pink wire connects to, is the door lights. I think all Toyotas door/dome light is pink. If you're not sure just unplug the connector and your dome light should go out.
You can find this plug in your Body ECU. Generally behind the glove box in most Toyota's.
Current model hilux is under the steering wheel. If you can see the fuse INJ it is the 5 pin plug just above. Pink wire is Pin 4.

I know you can also put an LED to shine on to your key barrel with this method.

Enjoy!

Nice.

I needs yaris, lol.

Great job man.

Just thought I'd add my bit to it to save you a bit of messing around in the future.

LED's draw very little amps so you can do away with the relay and hook it straight into the interior lighting circuit, and do away with the relay, fuse, and location of the power source. Depending on the size of the LED strip of course.

If you were to consider again replacing the interior lighting entirely with LED's, you would be able to place a larger, or even more LED strips in.

The average interior lighting fuse is about 5 amps. At 12 volts this works out to a total of 60 watts of usable power before you'll blow a fuse. The average light globe at 5 watts would only draw 0.4 amps, so theoretically you can install a total of 12 5 watt incandescent globes before starting to overload the circuit.

Check your fuse, and if you work on a safe limit of 10 watts of power per amp of fuse, you can work out the safe loading limit of the circuit.

Another thing to remember is that if there is a hidden globe somewhere (such as the one on the steering column for the key), you can replace this with an LED, or multiple amount as well if it is an incandescent globe. You'll need to use a resistor to drop the voltage so you don't burn the LED(s) out. Solder the resistor to the anode of the LED, not the cathode. To work out the size of the resistor, use this formula: Voltage supply minus the LED voltage drop, divided by the current draw.

Let's say you're using 3x 3.3 volt LED's connected in series. To calculate the resistor size would be worked out like so:

12 volts-(3.3 volts X 3 LED's for 9.9 volts)=2.1 volts. 2.1 volts / 0.02 mA=135 ohms or the next higher standard value of resistor. To be safe, take into consideration the charging circuit of the standard car which is 13.7 volts. Now, to calculate a safer size - 13.7-(3.3 volts X 3 LED's for 9.9 volts)=3.8 volts. 3.8 volts / 0.02 mA=190 ohms. When selecting the resistor, use the next highest value as they don't come in the exact value you require.

This is just a safer way of doing it. You can lower the value of the resistor slightly for a brighter luminescence, but you may inadvertently damage the LED.

If you take this formula to any good electronics shop, they'll be able to help you out as well. The current draw and voltage of LED's differ depending on the size, and the millicandela (mcd (brightness)).

Thanks Allen.
Yeah i know that you can connect it straight to the interior light, but i wanted to connect to it that i don't need to have the interior light(switched to DOOR) on for the LEDs to work.

I guess if you wanted to put a few individual LEDs down in to the foot well you will have to use a resistor. Just didn't feel like going through that process, so LED strips i went, and connected into series.

Got these LED strips from ebay for roughly about $1-2 each. Funny thing is that when i ordered 4 they gave 3 blue and 1 off blue which looks like aqua or green.

Will get pics up shortly.

I needs yaris, lol.

do it !!!

saw it working today and it looks real good so might get em done as well

[lunjiaow]

Haha. Dont believe you liked them. Thought you were going to say "RICER". At least it lightens up my footwell so i know where im stepping. Now my interior is not so plain no more. =)

[GreyWolf]

but i love rice, it goes so well with meats and vegetables

[lunjiaow]

Pictures. Should have done a video. But nothing special.

[NA_Goodness]

Wow... Big dejavu moment just there

Looks good! Ricey, but cool
