LED keyring light Installation *another koolkevin production!*
you have been repped. i just got it is it was a super easy install only took like 10 mins. only thing that happened to me is that my aftermarket alarm is getting confused now for some reason and doesn't want to arm. but ill figure it out tomorrow
alarm...
Hmm, that's interesting towelie,
I'd been having some weird stuff with my alarm also, but didn't make the connection. maybe the wires are used by the alarm system?
Maybe koolkevin can tell us what the wires in the steering wheel are for.
If it is some sort of wire for the alarm system, maybe it's not getting enough power, in that case, the probable solution is to increase the resistance of the keyring light, but I'll have to figure out what that should be.

That's it!
These are all gone (for now as far as I know... if people wimp out on me again a very small number will be available after the holidays).
Fear not though, if you want one, just read through the thread and make your own (it's easy, really)

UPDATE: so today after work i took my car where i installed my my alarm and i told the guy what was happing to my car well turns out the was that light is wired it interferes with ur alarm and ignition thats why the alarm was acting up. so i removed the led key ring light and BOOM! my alarm was working right back to normal. so i guess there has to be another way to wire that dam thing.
oh....
huh, I wonder if those wires are alarm wires... that would explain why they are powered when the car is unpowered...
If you'd like to wire the light to your dome timer, check post #21, but you'll have to extend the wires.

problem....
Towelie is right!!!
After looking over the service manual, I can see how it could (depending on how your aftermarket system, if any, is installed).
What happens is:
These wires are sometimes used to power the aftermarket alarm system. If you have one, then they keyring light and the alarm system are competing for electrical power. Some modern alarm systems use so little that the addition of the keyring light is enough to underpower the alarm system. This can cause the alarm system to not function correctly (see if the led is blinking or on or whatever it's supposed to do), and/or cause the alarm system to draw enough current to drain your battery in 4-5 days if you don't use your Fit.
As far as I can tell (I'm not an electrical engineer by profession, but I have some experience), this will only be a problem if:
1. you have an aftermarket alarm system.
2. you install the keyring light in the positions indicated my koolkevin.
I had been having aftermarket alarm problems, but I didn't make the connection until towelie wrote after taking his Fit back to his alarm place.
This can be fixed by:
1. rewiring your keyring light to the dome lights as in post #21.
2. rewiring your keyring light to your JDM foot lights (if you have them, just splice them right to the wires, check the polarity). This is what I did and it seems to fix everything.
3. if this is all just too much hassle, you can always do what the Honda engineers did and ditch the whole thing...
I'm sorry I didn't catch this sooner, I'm sorry for the hassle, and thanks to towelie for diagnosis.

So the led keyring light only has problems with aftermarket alarms then, most of us have the oem keyless entry. I guess the only other way is to wire it to a direct power source that gets constant power from the fusebox.
actually when my aftermarket alarm was screwed up by the light. i was using my factory one for like 2 days and even that one started to give me problems. the problem it give me on 2 ocations was that it didn't want to lock. i would press the lock button and it would luck then all of a sudden it would un lock it self all by it self.
oem keyless works for me...
in testing, I unhooked my aftermarket alarm, and my power drain problem disappeared.
The oem keyless system has always worked for me, and factory alarm system worked fine when the aftermarket was disconnected.
I should also say that this shouldn't be taken as a knock against koolkevin, who was very clever to figure out the wiring. If you don't have an aftermarket alarm system, I don't think you would be able to predict this could happen.

I don't have an aftermarket alarm but twice my car wouldn't start on Monday after only sitting for a few days.
I disconnected the keyring (hooked up the koolkevin method) and no problems for the past 3 weeks. Yesterday I hooked it up to the dome light circuit.
I sure did miss the glow when getting in after work at 11:00 PM. I'm glad to have the keyring back!

I'm not sure but I think if you wire the key ring to the dome light circuit like here:

Just thought I'd chime in, as I just fixed a battery drain problem with my fit.
With the keyring light attached as instructed (not to the dome light, in the steering wheel) and WITHOUT an aftermarket alarm (all stock sport alarm system here), my fit would drain the battery in 1 day or less, if it remained under 32F.
Well, turns out that the keyring light was causing my factory alarm system to get a little interested in the current draw (I guess) and caused an overall current of 0.25A when the car is off. I think that the current draw of these led's was just enough to keep one of the computers active and cause this draw, because there is no way that 2 led's will draw 0.25 amps without starting a fire.
I'm going to rewire these to the dome light when I get a chance, so it shouldn't be an issue then. Just thought I'd let everyone know about this.

may sound like a stupid question. or questions make that 
1. what wire I need 12g ? 14, 16, 18?
2. what length do i need to join onto the light wires, and get it to the dome connection point from fit of rage?
3. solder? any ? or just twist wire and black tape?
thanks all that contributed in this thread

don't worry about that.
This is a real lower power situation, it's not like you're wiring in a 100 watt subwoofer or anything. Even 24 will do fine. Take a look at the wires on the one I sent you, and look for something close down at radioshack or wherever.
It's about 20 inches, but give yourself 2 and a half feet, it's easy to cut wire away later.
definitely solder and tape. If you have one of the ones I made, I pre-tinned the wires, so they'll be difficult to twist with new wires.
Hope this helps!

sweet, thanks for getting back lubricus. I really appreciate all that you've done with doing the lights and all.
one other thing I seen on a japan diy site is they took the plastic part that surrounds the key hole and and made it bigger (more light I guess ? ) by wrapping sand paper around the tapered neck of a bottle.
I also found a chrome ring to go around the whole bit when done
