: Interior lighting help, please
03-11-2012, 11:15 PM
Hello there, I need some help with installing some simple LED lights in my 2008 Focus S. The LED lights are simple ones I got from my local Canadian Tire, they plug into a 12V outlet or cigarette outlet. I used that for a bit, but I want them to turn on when I turn my night time lights on. I tried tonight to figure out it on my own, I pulled out the selector switch and I skinned part of two of the wires that I thought were the correct ones but no go. Now the lights are a simple set up, 4 LEDs connected to a small circuit board with a on/off switch and two wires connected to the positive and negative contacts for the 12v plug. I don't know what else to say, if you have more questions I can certainly answer them to the best of my ability. Any help is welcomed! Also I did try looking in the self help area and couldn't really see anything pertaining to this. Thanks again, Justin

[welcome] to the site, I will look at my Factory Wiring manual tomorrow and let you know what wires to look for, that is if there the same as a 2010.

No one has any ideas on what to do? or what wires i should be looking for? i thought this would of been fairly simple for a form full of intelligent focus fanatics.

Ok Here is a photo of the Ford Focus Factory Electrical Wiring manual (2010 model) of the factory interior upgrade lighting.
here is were the factory lighting would hook into.
Im guessing the wiring you want to find will be attached to the center console under the radio. Your looking for a Blue wire in the cluster.
It would be somewhere around one of the 3 button clusters at the bottom (here is my stock center stack for reference)

You could always just wire it into a new switch/button and mount that on the dash somewhere then wire directly to the battery. That's what I did for my LED's.
I have the schematics for the fog light selector up on my How To install them but not too sure which wires are for the regular headlights.
Here is the link to the how to, if it helps. I know one is for power but not too sure which one.
Click ME! Schematic is near bottom of guide. (http://www.focusfanatics.com/forum/showthread.php?t=267177)

I have those diagrams as well, let me know what you need. I have the whole book. Now my book is for the 2010, but Im sure the other years are the same or close to it.

ah, see that schematic is perfect. When i first tried it, i tried using the wires right behind C205 main light switch. There is lots of room for the LEDS circite board to go, and the wires are easier to distinguish and find haha, so if you have the schematics for the C205 the main light switch, that would be super awesome. Also, i could do the switch idea, but then it wouldnt be much of a difference from just plugging them into the 12v outlet. I just like the idea of the LEDS coming on when i flip on my night time lights.

Here is the C205 plug diagram
Also this would be the factory plug for the Ambient Lighting control, and is already there. You would just have to hook into it like the factory would.

alot of parts stores like autozone oreielys and pepboys have them also

yes you can get a repair manual from there, but I'm using a real Ford Service Manual! I consider them first as they built the car.

just a thought...couldnt you just t-tap into a fuse...like the parking one or something?
03-13-2012, 09:17 PM
Sure you can, I was just showing where the correct wires are at.

WOW! Bob you are awesome and know how to show a newbie like me that hes welcomed, those diagrams are great, and I now know which wire to tap into behind the switch :). Question tho, what exactly is the ambient control switch? It doesnt seem to be a visible switch from the diagram of the wiring harness. So does that mean its hidden right behind when there Pass. airbag light is? And do you think that is controlled by the turning the parking lights/night time lights on and off?

So i have given up on trying to make this work, I think i will stick to plugging it into the 12v for now, maybe one day i will try something like this again, till then time to start on new and better things

I'm trying to do the exact same thing as the OP, and I can't make it work either. I've tried splicing into several wires behind that switch, and nothing seems to work. I have an LED in-line switch that is turned on, and when I flip the headlights on the switch lights up. I'm then able to turn the switch on and off, but the strip lighting I have doesn't light up.
I've got it running directly off the battery for now, but I really would rather have it pulling from behind that switch, with the in-line LED switch to turn it off when I end up getting tired of the lights every night.
So far I've hooked my red wire to Headlight - ON and black to Ground in pin #10, that didn't work. I also tried Headlight - OFF and ground to pin 10 again and that didn't work. Everytime the switch will light up so it's pulling power when the headlights are turned on, but perhaps it's not pulling enough voltage to power the strips? I don't have a multimeter to test how much voltage is running through there when the headlight switch is turned on though.
