    I just cut that green/red wire and did not install the switch and tested everything, and it works. No more DTRL :kona:

    I too want to know what the drl line exactly does. I realize this is not an engineering forum so I don't expect people to question how things work and just simply accept things as is. But I'm sure there are quite a few other curious minds out there.

    I need to borrow a 12 pin flasher to reverse engineer this.

    see my other thread
    http://www.tacomaworld.com/forum/technical-chat/322858-how-does-drl-signal-body-ecu-work.html

    I took your test one step further and used an oscilloscope. I only get really low voltage readings (I think these are just noise) when I examine the drl line.

    this is with headlights off

    this is with headlights on
    [​IMG]

    the voltage level is less than 0.5v, so I can't say for sure these are actual signals and not just noise.

    I HATE the DTRL's so I was pumped to find this thread. Total newb when it comes to wiring so I have a question...

    After removing the coin tray I see that one of the harness plugs has a green/red striped wire, shown in my pic below. After re-reading the 1st page of this thread and see the pic, it says the wire is found in a plug on the BACK of the fuse block. The wire I found is in a front plug....please someone let me know if what I have is the correct wire or not before I cut...thx

    In my 09, that wire was apart of a harness with 3 different plugs on it. I just unplugged all those and took the harness to my kitchen table and made everything a whole lot easier.

    Thanks guys...I knew what I found was too easy:p I'll see if I can pull the one from the backside. I just want to cut the darn thing to be rid of them.

    Update - I am way too fat and my head is way too big to get my ass anywhere near seeing the back of that fuse panel........

    2nd update....finally was able to contort myself enough to get to the wire and give it a clip. I just wanted them gone so I just taped them off - no switch for me.

    Thanks OP for the info.

    Hi Crom,
    Thanks for the write up on this. I am going to get going on this mod soon.
    I have a couple of questions before I start dismantling my dash and snipping wires.
    I have the DRL set up along with a oznium rocker switch that I am going to splice in before plugging it in.

    Once I get this done, I am planning to switch out the bulbs with some of Jumpers LEDs (switchback specifically) so I don't get the melting lens mod.:)

    - Will the on/off switch affect anything with the switchback LEDs, that you know of? I will ask Jumper too, if you don't.

    - What gauge wire would I use to splice the switch in?
    - Where would one find the Molex type connector that you used, if one does not have resources in their shop?
    - Do you think a place like RadioShack have this stuff?

    This is my first real electrical system mod to the truck, so I am trying not to fahk anything up and I really trust and respect your work.

    Thanks for the help.

    No. Should not affect anything. I spliced LED's into my turn signal circuit 5 years ago. Work great to this day.


    22- 26 AWG is a good guess, it's whatever gauge Toyota is using in the wiring block.

    Search amazon for "2-pin connector" you'll see plenty of options. Light weight connectors are good for this project. I harvested mine from an old computer fan.

    You're very welcome. I think you'll do just fine. Glad to make a positive contribution to the TW community.

    Did mine this past weekend. With I would have done it years ago. I wouldnt be on my 3rd set of headlights. At least I have some new ones coming in at the dealership for free.

    Thanks to all of the previous posters. The mod was quick and simple. I put the rocker up by the fog light switch and tapped into an unused fuse on the block to power the LED in the switch.
