Default Interior lighting question.

I have LED strips hooked up to a 12v constant through a switch, but I want them to come on with my dome or better yet when a door is open
( regardless or the dome being switched to door or not) .
I attempted to locate the door sensors but I dont know where to locate the ground that makes that light on my cluster turn on/off.


Id like to avoid running wires from each door , so where am I looking?
I found some diagrams and such but, even with the slight knowledge I have on reading them, they confuse me.

I found this box that a few people refer to as the " BIU " it supposedly controls the dome light when doors are open. But using a "t" tap on the wire I was referred to did nothing.

I've been on Iwsti and I found the diagrams on North Ursalia, I've searched here, and found nothing thats of any real use.

So forum, do you have anything?

My info shows the return side of the dome light ties to pin B3 of the BIU and is a blue/red wire. By applying constant power to the other side of the LEDs and tieing the return side of the lights to that pin connection the lights will turn on when any door is opened and with the dome light switch in any position.

If that is the way you have it wired already then you may have the LEDs reversed. By just manually grounding the end of the wire to the lights they should turn on if the lights are ok and have power getting to them.

Naw, not really. It's just wires. Glad you got it going.

Just to clarify, return side means ground wire right?

That's right. The return side to the battery.

So theres no b3 pin out on b281 ( blue connector) I have the red striped blue wire connected with nothing and my dome light will only work if I turn it on ( with no reaction from the L.E.D. )

1.I checked the wiring from Power source to LED, they are wired correctly ( they are able to turn on )
2. The BLUE wire with the RED STRIPE, is b1 I believe.
3. I was told to use b5 when I first started this project ( before this post ) It will not work either.


So to sum it up, I fooled with the blue connector on the BIU , b1-red stripe blue wire , and b5 blue wire, the dome light wont work now when doors are opened and switch is on " DOOR ".

Cougar4 I need you !

Check fuse #2 in the dash panel and see if it is blown. You may have shorted something.

After looking at some other info I see what you are saying and it shows a blue wire going to A5 of the blue connector and it ties to the dome light return. If grounding that wire doesn't turn on the dome light with the switch in the door position then the light is bad, fuse 2 is bad, or something with the wiring has failed.

Okay, Im back with an update.
Checked EVERY fuse on the interior fuse box.
Checked the engine bay fuse box.
Still getting nothing with this deal.

Ive been reading diagrams out of hanes books but it seems to general so I havent put it to use.
Still have no dome light when door is open. ( manually turned on/off only )
Its frustrating to say the least.
As most project turn out to be.

Let LED's light your way!

You're trying to use the integrated module to get your LED's to turn on/off when the door is opened/closed.

Connector B280 is blue and B281 is grey (and I don't know why two different ones are listed).

Regardless, the blue wire that goes into A5 is the ground. You want to test this using a logic-tester and not a wire-tester. A logic-tester can be used to test actual power circuits as well as for computer/ECU circuits without blowing anything out.

A logic-tester has a red and a green LED on a printed circuit-board within the clear handle itself. When you hook it up to the car's battery, it will illuminate green for ground and red for power when a circuit is touched by the probe-end.

Use this to test A5.

Test it with the door open and you will note that logic-tester will illuminate green. Then have someone push the door open switch plunger to open the circuit. After 30 to 60 seconds you will note the green indicator will go off because the integrated module will time-out.

Once you have determined that A5 is the actual ground circuit, you'll want to hook up the LED's ground wire to this. The power side of the LED's you'll want to hook up to a constant power source.

This is what I did on my 2006 WRX. I put LED puddle lights on the back side of the center console side panels to illuminate the floor and they come on when I unlock the doors with the key-fob and they will go off once the doors are either locked via the key-fob or they will eventually time out vis-a-vis the integrated module.

I'm going to do some other wiring mods to the car this weekend. If I remember, I'll take a pic or two of the integrated module showing where I tapped into it.

Big-E's suggestion of using a logic probe is a very good idea but unfortunately not many folks have one on hand. If you have a voltmeter please check the voltage on pin A5 of the integrated module while the doors are shut and the dome light switch is in the correct position to turn on the light when a door is opened. You should have close to 12 volts on that pin with the doors closed. If you don't have 12 volts there then the wire between the light and pin A5 is open. If you do have 12 volts on the pin and open a door and the voltage doesn't change then there is most likely a problem with the integrated module.

hm, maybe able to help if you never got this working. I went to Autozone yesterday and bought a set of the led strip light (red). I wanted them to come on when i opened the doors and fade out when i closed the door, just like the dome light. I put these in my footwells inside. To do this i found the box under the dash that makes the annoying chime when the key is in and the door open.

There are 2 connectors on the box, *working on a 2005 wagon. The plug toward the passanger side is the one i tapped into. I used the LR wire (blue/red stripe)(+) and the LW(blue/white)(-) wire.

this worked like a champ for me. I would like to add a constant on switch to this soon but this may require a diode inline to keep Voltage from coming back, we'll see.

If this is of help to you I can take a pic and send you a copy of the wiring diagram I used.

Has anyone installed these? What's your opinion? Has anyone tried combining both the red & blue lights together? Can the cubby light in the center console power both sets of reds and blues?

Thanks
