This is my first time writing up a DIY so, if im missing something or not explaining clearly, please let me know.
I don't have a whole lot of pictures for this, as I did not thought about writing up a DIY at the time. Sorry for the lack of pics.
*It is recommended that you read through this DIY before purchasing any parts and tools.
**Time consumption: really depends on your ability and knowledge with wires and electricity. It took me 3 days, around 2 hours each plus running around for materials, to figure it out and make adjustments accordingly, but with this guide it should take you around 2 hours for the complete job.
***This setup only works if ignition is on. To make it operate with dome light and doors you will need to wire them to dome light, and some other stuff. that i am still educating myself on

im going to split it into a few sections (so that you can find what you need without reading stuff you dont need):
A. Background
B. Tools you need
C. Procedure

A. Background
Well, i've always wanted to have floor lights in my car, but i was not 100% sure about how to do it and if i am capable of doing it even with the light strips and tools at hand.
i finally decided to do the floor light after the week-long trip to San Francisco at the end of 2012/ beginning of 2013. My friends and i rented a ford escape and it has lighting package (floor lights, cup holder lights, center console lights etc) and i loved it.
So i started researching once i got back, started a thread to discuss possible plans and getting myself educated (thread located here: http://www.toyotanation.com/forum/103-3rd-4th-generation-1992-1996-1997-2001/439889-floor-lights-gen-4-a.html) and messed up a few times. but hey, it's DIY, learn from your mistakes, right?

2. Tools you need
-LED Strips
I ordered mine through V-leds.com. i got 4 strips of 6inch 6K white. however, these come with pin heads that will require some modification before you can use them. i forgot how much i spent on them
Image

you dont need to get them from v-leds.com. any strip that fit your budget and need will do.
-wires
i used Cerrowire 65 ft. 20/2 Bell Wire from homedepot. i heard that speaker wires work as well, but i don't know. this costed me around 8 bucks
(no pic for this, just go to homedepot.com and look for it)
-E-tape
-wire-stripper
-Flashlight (to see better, this is optional)
-impact wrench
-on/off switch (part number: PT297-89013-sw) costed me about 13 bucks
-inline fuse holder and fuse (i used 7.5 amp)
-9V battery (does not need to be new)
-Screw driver

C. Procedure
1. disconnect the car battery. This is extremely important and i learned the lesson the hard way.
2. run the bell wire from your kick panel fuse box, under front seat, around center console (from rear seats), then under front passenger seat, then finally under the glove box. for future reference in this DIY, i will call it "main wire"
*Suggestion: run more than you need. you can always adjust the length and you will need to cut them to connect to your LEDs anyways. (no pic for this)
3. now the hard part. If you have the v-leds.com strips, cut off the pin head and strip the wires so that you have loose ends, then use a 9V battery to find out the positive and negative wires. cut a short segment of bell wire, about 4 inches long, and wire them to your positive and negative of your LED wires. Use the e-tape to secure the connection. Test with the battery to make sure connection is secured. Repeat for all LED strips.
*if you got bad eye sight or big hand, you will spend quite a lot of time on this.
4. Now, connect them to the main wire. Positive to positive, negative to negative. To do so, you will need to cut the main wire at the location where you want to install your LEDs to create an intersection for the current. For instance, for positive wire: one from the main wire, one from your led strip, and one to carry on the current onto the next LED.
Twist the 3 wires together and secure the connection with e-tape. Do this for all positives and negatives (positive to positive, negative to negative)
*For the front passenger side, you don't need to cut any wire as there is no place to lead the current to, so just connect the end of the main wire to your led strip to create a loop.
*power source (+)-> first LED(+)-> second LED(+)->third LED (+)-> fourth LED (+) and (-)->third LED (-)-> second LED (-) ->first LED (-) -> ground (-)
**At this point, you should be adjusting the length of the main wire.
5. This step will guide you to install an on/off switch and fuse. if you dont want to use the switch, skip this step.
There should be a black rectangular plastic peace right next to the dash dimmer. Push it out from inside the kick panel.
Then, hook up the positive wire from your main wire on to the switch. it doesn't really matter which pin you hook it up to.
To hook up the inline fuse holder, you need 2 segments of wire. Strip them a bit deep, and twist them to both sides of the fuse holder, and then hook up one of them to the switch.
A diagram would look like: wire(+)->fuse holder(+)->wire (+)->on/off switch (+)->main wire (+)
After you are done, push the switch back to the empty slot that you just created from removing the rectangular plastic piece
6. Tap it into the gauge fuse slot. Search the internet for how to do this.
if you have on/off switch, the diagram looks like this:
gauge fuse slot (+)->wire(+)->fuse holder(+)->wire (+)->on/off switch (+)->main wire (+)
if no on/off switch, then:
gauge fuse slot (+)->main wire (+)
gauge fuse is only live when ignition is on. i haven't found any fuse that is hot in the kick panel box that is live all the time. (if i do i will switch it, i got the on/off switch anyways)
7. ground the main wire.
to do this, you will need to find any naked bolts connected to the frame. I used the screw that secures front seat rail on to the floor. You will need an impact wrench to loosen the screw, put the ground around the screw, then tighten it.
8. connect your car battery, test it out, stick the strips on desired location, and you are done!
*If somehow it doesn't work, check for loose connection on "intersection" wires (places that connect the main wires and LED). always check from the driver floor, as this set up is a serial circuit.

(i redid the wire on front passenger side, there's no wire visible now as they are all under the floor mat)

you know you could also run the wire for the driver side down underneath the trim panel on the driver side where you had the original switch. theres clamps holding a wire harness etc for speakers etc etc
im not 100% sure what you're talking about lol
what trim panel are you talking about? a pic might help

Nice Mod!

I just recently installed some hot pink led under dash lights in my sisters car. I got hers off of ebay though.. Had the LED strips, wiring, and control module all together. They are kinda cool, there is a control switch that allows you to have the light go with the beat of the music, or other random variations. I'll have to record a video of it sometime. I wired it up almost exactly how you did. Only difference was I used a generic toggle switch for the power.

ohh that piece. yeah i realized that i could run it under that piece after i'm done with the entire thing, and i'm just too lazy to redo all the wires just to hide them.

now if i'm gonna hook them up with the dome light, i would defiantly run the wire under the trim. but as of now, i have no idea which are the wires that feed power into the dome, nor how to connect to the dome and hide the wires.

thanks for making a video though:thanks:

UPDATE: I found the dome light connector, got leds (a spare wrong led strip for my aftermarket spoiler) to stay on when the door is open and off when you close the door) and I got a 3 way scion switch from oznium that fits perfectly with the blank spots (literally the exact same dimensions as the oem fog switch) XD just waiting on the leds tomorrow

the wire with the connector is the + for the dome
Image


I used a different connector to tap into the - wire

Image


general pic of where the plug is (sorry about the night pics) ill update with day pics in a little bit
Image


I ran the cable to the left of the block down towards the kick plate and actually used two plugs and the bundles to loop the wires through to hold them )

Image


pic of led strip just connect to the plug (note: the dome switch can be off or on and the leds work! :))

Image


I started to snake the wires under the inside weather stripping but just ran them through the wire loops instead (you can do either or)

Image


Image


Image


Ran the wires under the carpet to the slit in the carpet where the driver side floor vent is and passed and under it to where the center console is

Image


Image


Image


Ran them around the back of the center console area and carefully snaked the wire through the loop nicely created by the blue electrical tape that had lost its adhesion (its the black plastic wire holder towards the middle right)

Image


Image


Back under the passenger side vent

Image


Up the passenger side

Image


Didn't take a pic of the passenger kick plate but basically just bundled all the extra wire and stuffed it under the black plastic cover under where the blower motor is (until I get the leds)

a pic of the scion 3 way switch from oznium with the oem fog switch for comparison (its the on/off/on switch that's 12$)
http://www.oznium.com/gsw-45
its 12.99$ and the middle option on the top right side of the page

(3 way switch on the the left)

Image



Never mean't to hijack or nothing (been in contact with ws6616 updating him on finding the wires for the dome light since that's what he wanted to do originally) and basically just building upon and improving his original diy

Hope this helps you guys!
