need help with wiring for my car project

[Kevin Van Sant]

I've posted this to a couple of honda forums but I thought I'd try a
couple of electronics forums too. Thanks for any help.

I undertook my project of adding a map light assembly into the
headliner of my 98 civic LS today. I had to remove all the upper
interior trim to pull down the head liner, but it wasn't too bad. I
mounted the map light assembly and have put everything back together.
I haven't figured out the wiring, maybe someone here can help.

My Civic LS 4D is a '98, the dome light has two wires only. One leads
to the battery + , the other comes from the door switches. (I have the
'98 wiring diagram) The grounding comes from being screwed to the
metal frame of the roof.

The map light is from a 2001 Civic EX 2dr. There are 4 wires (see
picture)

From looking at it, I'm thinking black is ground, red is (+), but
there is still blue and green. Green is possibly for the door switch
lead, but what about blue which is tied into yellow (thus tied to
white)?

I have to make four wires become three. I'm either going to have to
tie two or leave one out. Anyone have any clearer idea of this than I
do?

As a follow-up, I decided that blue and red were both (+) so tied
them together to the (+) lead. Black was ground, green was door
switches. I wired it up this way and the map lights work, the
original dome works, but the new dome blows the fuse when I turn it
on. The new dome is what's related to the blue wire (if you look at
the picture it should be clear) So evidently I can't just tie it to
the red, although if I exclude it there is no (+) lead to the new dome
light.
Can anyone figure out how I might wire this differently? Thanks.

Without seeing your cars wiring diagram I can't help.

Your light needs only +12 and vehicle ground.
Where you get them is another matter.
Sometimes the vehicle supplies a shutoff delay +12 or a dash dimmable +12
and usually an accessory key position +12.
I don't know what you want.

Wow, have you really nothing better to do? I'm just trying to get a
little help for a project I'm doing. I posted my query to a couple of
relevant usenet groups as well as a couple of web forums. What's your
problem? ...actually, please don't answer.

I'm just trying to get a little help

I pointed out a way to get BETTER responses.
You can, of course, choose to remain ignorant.

you need a better hobby Jeff. This is just a one time foray for me
into a couple of electronics forums to try to find an answer to a
specific electric problem. I posted in 3 groups, if I had
crossposted it still would have been 3 groups. I prefer not to
crosspost, in my experience it is better not to introduce the wackos
from one group into another. For example by not having crossposted
I've spared those in the other two electronics groups I posted to all
this crap.

btw If you know anything about electronics I'd be happy to hear your
solution to my wiring issue. Otherwise just press delete and move on.
I'm sure there must be something more pressing you could be doing
with your time.

I know I've got better things to do than read your posts multiple times.

His problem should be pretty apparent from the links in his post. But
I'll tell you what his problem is anyway: People like you cluttering up
usenet with multiple identical posts. It's not just his problem, the
hundreds or thousands of other people who subscribe to more than one of
the groups to which you sent your message will have seen it multiple
times for no good reason too. Learn to cross-post. Please.

More fool you in this case.
The sci.electronics.* whackos are already acquainted.

This is just a one time foray for me into a couple of electronics forums

The name alone of one of the groups should have clued you in
that an automobile wiring question was off-topic there.

btw If you know anything about electronics
I'd be happy to hear your solution to my wiring issue.

The solution has been offered TWICE.
That you are too lazy to follow it
(your public library has Mitchell Manuals under R629.129)
or too ignorant to recognize it as correct are separate issues.

In addition, since you selfishly chose to MULTI-POST,
at the time, neither poster knew about the other response
and the same (correct) answer was repeated.

MULTI-POSTING IS STUPID AND SELFISH.
READ THE THREAD AT THE LINK TO SEE WHY.

the subject of electronic circuit design is precisely why I included
that group. I figured anyone who designs circuits would see very
clearly what was going on with my project and find it very simple.
It's not my thing so I was appealing to experts. It worked.

The solution has been offered TWICE.
That you are too lazy to follow it

I read and pondered every suggestion posted. The solution actually
turned out to be none of them. At least not directly... they were
helpful though. I did get it figured out and it's working perfectly
now.

I'm happy for you that your world is trouble free such that you
consider a one-time lack of crossposting a problem significant enough
to get worked up over. But I'm through here in the electronics groups
now, my problem is solved. So I guess that means yours is too. I'm
sure you'll find another cause to champion soon enough. Next time I
have an electronics question I'll try here again. Maybe by then
you'll have some perspective.
