tapping into door interior light

[XP02ED]

hey guys just need some advise.

trying to tap into the door light wire, so when the door opens additional light goes on..

anyone got any idea where this can be foind for the + for the wire.

it aint where the door sensor is, which i initially thought that!

[EuroDude]

Where is the additional light going to be?

If in the door, then you can take off the inner door panel/cover and tap into the wire that leads down to the original door light.

If the new light is going to be in the cabin somewhere, then you need to tap into the wires than lead into the door near the hinges. But it may be easier to tap into the interior light fuse circuit in the fuse box under the dash if there is a spare/empty fuse connector that activates when the doors are open. Or alternatively you could tap into any other light that turns on such as the one in the roof.

[XP02ED]

yeh thats what im trying to do

basically put lights where the pedals are right

trying to tap into the wire that the cieling lights use so when doors open it lights up as well!

i tried to use the line from the door sensor on the side panels but i think maybe thats just a sensor coz it didnt work!

any1 got any ideas where the positive (+) line from the cieling line goes to?

[EuroDude]

The wires are usually routed through black plastic corrugated tubes so what you need to do is dismantle the roof or door light and look at the colour code on the positive wire, then trace the wire into an accessible part in the cabin, such as under the dash (or maybe within one of the B Pillars behind the plastic cover), then open up the plastic tubing and locate the wire with the same colour code, and tap into it. Not sure where the tubing routes through the car though.

If you rip off the plastic covers that hold the carpet in under the front doors, you should see some plastic tubing with wires in them, the wire (colour code) you are looking for may be in there.

[XP02ED]

yeh done that.

basically there a wire from the pillars for each side right. which goes to under the dash to a connecter.. which it looked like it connected to the signal light switch area.. that got me stumped.

i tried to see if its the wire to use which it wasnt..

so im trying to get the wire from the cieling where the actual light is..

habnt taken my roof out.. so im wondering where that wire from the cieling light goes to

if you know what i mean

[destrukshn]

why don't you just go from the door light swtich?

[EuroDude]

Yeh not sure where the roof light routes to. I guess the easiest way is to take off part of the room lining and see where it goes.

Soldering your own wire into the roof light connector and routing it down the middle-right pillar might be the easiest way to do it, unless you can find a wiring diagram for the EG. eBay should have an EG workshop manual that contains wiring diagrams, although sometimes those diagrams only show the circuit, not the car locations of the actual wires.

[EuroDude]

why don't you just go from the door light swtich?

He has already tried the door sensor, I dont think that's 12v powered is it?

[destrukshn]

it's negative.
hooke the negative to that, and use a constant positive.

[XP02ED]

OH!

so that wire is ground?!?!?!?

OH MAEN i never checked that.

so thats the ground which grounds the wire?

BUT what if the switch is hit to be ON all the time.

[destrukshn]

then your other lights will be on
when the interior lights, then your other light turns off as well.

[EuroDude]

Pretty sure the door sensor is a reversed switch, i.e. its powered/continuous when the door is open, instead of closed. It has nothing to do with the "always On" roof switch.

[destrukshn]

what do you mean?
that's what he wants right? when it opens up, the lights turn on, meaning it's earthing out to complete the circuit.

[m3ntAL_l2]

alright this is wot i did when i wired up my neons under the feet bit in my dc4, i taped the wires to my boot lights, cos in dc4 the boot light comes on aswell when the door opens, -ve and +ve is already teher, no probs so far

[destrukshn]

yeah that's fine as well, but that just means running longer wires, and taking off more trims.

[m3ntAL_l2]

yea but its alot easier than takin the whole door off n findin teh wires n stuff... lol im lazy, + the wires came with teh neons were longer enough so y not...
i didnt take off that much trims, cos its running together with my sub wires... so yea

[EuroDude]

lol confusing.

If you also want to add a switch to your light, then you simply add a second earth wire, one that is always connected to earth. The other earth wire of your switch goes to the door sensor so it only activates when the door is open.

[destrukshn]

a switch to turn the lights on any time?
or to turn em off even though the doors are open?

to get to the door light switch, you don't have to open the door trim
plus honda trims are a piece of piss to take off.

[EuroDude]

I'm guessing a switch so he can keep the new light lit even when the doors are closed.


Is it a Civic hatch or Sedan?


If the boot light in the EG lights up when the doors are open (I dont think my EG/EH sedan did that) then have a quick look at the colour code of the boot light wire, and look for the wire in the plastic tubing running thru the side next to the door, and tap into that.

[XP02ED]

WOW, this is getting to a different story! LOL

Sumamry : Installing Neons to be exactly on at the same time the cieling light turns on.. i am riding on a EG hatch..

Quick help : is the door sensors on the sides ground or + ?

If not where do i connect the + and the - so it turns on exactly how the cieling light is..

once its alwaiz on.. the neons are alwais on..
if its on door mode.. the neons turns on when door opens.
if its on off.l,, neons dont turn on!

wire from each side from memory is blue stripes on green and yellow on green I THINK! thats from the door sensors.. but it doesnt look like i got a + on it when i tried it.. didnt have a tester on me so couldnt tell!

[EuroDude]

In that case then the easiest way to do it is run your own wire straight from the positive terminal of the bulb in the roof, then down a B Pillar.

[XP02ED]

yeh very true..

i dont have time to take of the roof!

basically where do i find the wire for the positive end of the bulb !

[EuroDude]

You need to dislodge the roof light assembly to access the wires. Not sure exactly how its designed, but I imagine you need to flick off the clear plastic cover first, then unscrew a couple of screws so the assembly can drop down.

[XP02ED]

hmm>??? no no

i mean.. there has to be a wire somewhere else where it leads to besides taking the roof of.. i guess any1 got a diagram or a link to one which points th wiring diagram of the cieling light for a EG?

[CRXer]

Guys,all very simple.

Its all at the under dash fuse box.

For positive(12V),get a female spade terminal & plug it into one of the spare terminals on the front of the fuse box,theres about 5 of them.One or two of them will be permanent supplies,the others will activate at various positions of the ignition key.Just test which one is on all the time.Also put an appropriate fuse in this wire,& then feed to the lights your installing.

Yes the door switch is a ground switch.It grounds the lights so they can activate.
This wire appears at the integrated control unit clipped into the rear of the fuse box.It will be in a connector ,seperate from all the other rear connectors,plugged into the back of fuse box closest to the passenger side.

Most likely a green/red wire(check what colour it is at the passenger door switch,not the drivers door switch).Just tap a connection off this to lead to the lights.Test the wire grounds out when u open & close the door by pulling the connector out & testing,before u cut anything.

[CRXer]

I got a spare DC2 fuse box here,let me know if u want pics.

BTW the ceiling switch will not affect the lights if u install this way,if u want them to come on with ceiling switch as well,then u need to run a wire up to the switch.

[XP02ED]

ooo ok so basically..

the wires which is on the door sensor is the ground..

grab a positive wire (prolly just connect directly to battery? or any suggestion where exactly i should connect too) with a fuse between?

if this is wrong let me know!

**from your update**

OH MAEN! so i need to grab the + from the ceiling?

[CRXer]

Hang tight I'll grab some pics,easier.

[CRXer]

What i meant by the ceiling switch,is if you want to be able to turn new lights on as well by flicking the switch to 'ON',then u need to run a wire to the ceiling light.

If your satisfied to just have them come on by opening door,then just tap into fuse box wiring.

Or u could just add a seperate switch in the ground wire to lights,with a seperate permanent ground feeding onto the switch,to toggle lights on/off at your leisure.

[XP02ED]

wow nice!

hmm aiight will look at how it goes tmz! thanks!

[XP02ED]

ok

what i did.. i didnt exactly follow what u posted crxer as i dont wna take my fuse box apart or pull it off..

i basically wired the + to a alwaiz on line, ie my fog light power source/amp powersource

then i wired the ground to the wires (2 from each side of the door) !

[destrukshn]

so like what i said?
lol
.

[CRXer]

U dont have to pull anything apart,just disconnect the plug from the back of the fuse box to make it easier to tap into the door switch wire & plug one wire into the front.

Not quite sure what u mean by "2 from each side of the door",but if u done what i think u done,u might find yourself getting sick of the key reminder & lights left on buzzer going off everytime u stop to let a passenger out of the car.

[XP02ED]

heheheee

there 2 gground wires, 1 wire from the sensor at the passenger door the other from the drivers door which connect to a plug then output as 2 wires too which is wierd

yeh my car buzzes all the time when lights are on and doors open! its ***n annoying BUT hey it reminds me that i left my light on!

[CRXer]

U only need to connect to the passenger door switch.

The drivers door will still activate the light & your buzzer reminder circuit will work as normal,but u wont get that annoying buzz when u drop off a passenger & your trying to talk to them while they still have the door open.

[XP02ED]

oh,

well what i did..

the 2 wires connect into a plug which come from another 2 wires which my alarm is connected to, i basically just connected to that single wire that my alarm uses?

should this be ok?

========PLUG===(at this point 3 wires)

1 alarm wire
1 from passenger ground
1 from driver ground

[CRXer]

Just cut the wire going to the drivers side,u dont need it.

The only diff with the drivers door is it goes thru the control unit on the back of the fuse box to set off your warning buzzers on the drivers door only.

The lights & alarm will still work for the drivers door if u cut the wire,but the buzzers will revert back to drivers door only like theyre supposed to.

[XP02ED]

oh really

ooo MAD! THANKS! might give that a goe once i fix my interior light LOL

coz i keep forgetting to turn my lights off! buzzers helps at this point
