No, I'm not asking how to install the JDM Foglights, these are the SIDE foglights that are in the same location as USDM turn signals.
Take a look at these pictures, tell me if you have any idea on where to get more information on this purchase I just made. I don't know exactly how I'm going to wire them up and haven't found anybody on PO with them yet or a writeup on them.
The basic background on these was that they came as an option in Japan so that as you turned a corner, these side lights would illuminate and show the rest of the road on the side you were turning to. It was kind of a big deal at the time I'm sure, before Lexus started the whole trend of mainstreaming "swiveling headlights." So I'm looking to find out what triggered these to turn on. I know it can't be the activation of the regular JDM driving lights (see: JDM Foglights) because I don't think you'd want both of these on going down the road. They should only come on when you're turning and therefore it makes me wonder if they had to connect into the turn signal's "signal" in any way so that if it wasn't as advanced to tell which direction you were turning, at least the activation of the turn signal would tell it which one to light up until the turn signal was turned off.
This may not be an official answer; but personally I'd use a relay off of the power steering pressure switch; with the hot coming from your fog light switch.
Wiring them up that way would make them turn on every single time he would turn. Great if he wants that, but the original function was that they would turn on with the turn signals.
the only thing i can think of at the moment is a combination of a capacitor and a relay. when the signals engage they send a pulse to the indicators, so if you just used a relay the foglight would blink with the indicator. but if you place a capacitor in between the indicator and relay, the capacitor will charge and release a steady stream of 12v (assuming you buy a 12v capacitor).
this is the simplest way i can think of, there's a way to use just relays but you'll end up having like 3 of them for one corner fog.
Thanks Shimee, do you have any brands you trust for capacitors or relays that would be a safe bet for me to check out? This sounds really great and I want to do it right the first time.
Does anybody else think that this idea will or will not work before I would buy them?
jdm cars have another harness coming from the turn signal relay. it's a negative switched relay. it'd be 10x simpler to run 2 negative switched wires from the negative wires running to the blinker/turn signal relay to 2 dioded relays running to the lights. gl.
hell i'd buy the damn things even if you can't figure out how to install them.
for some reason i'm thinking we don't have the proper function in either our ecu or fuse panel. because as a human its pretty easy to execute the function; "ooh it's blinking, ok keep this light on!" but in the electrical sense it's kind of confusing. so i'm wondering if on the JDM ecu there was a "sensor" that would turn on the foglight in the scenario i just described.
as far as capacitors, i really don't know. it was the first thing that came to my head but i actually haven't played with capacitors in an automotive setting. the only other thing i can think of is some custom wiring to the indicator throw switch on the steering column.
the honest answer is that it will take some ingenuity and effort to get these to work on a non JDM prelude without the proper wiring.
Ok... if you want either fog light to come on when your fog lights are on, and the respective blinker is on, it should be pretty simple:
Tie 2 relays that connect when you turn on either blinker, that feed GROUND.
Wire the switched ground to the ground on either fog light; and feed the + line from the fog lights to the other fog lights.
You might not need relays; but its safer to use them anyhow..
The Left/Right Constant + lines are the GRN/BLU and BLU/GRN lines that run to the TURN SIGNAL/HAZARD RELAY in the under dash fuse/relay box. You can use the BLK that runs to that same relay, as a ground for the relays.
You can pickup some cheap 10a relays at radioshack for $2 each.
oh congratz on the pickup. i didn't realize the auction ended
if you can't figure out how to do it and you wanna do it by relays, i can have my friend figure it out and give you a list of parts to get from radio shack
as an Electronics Engineer; I created a messy, ugly wiring diagram for it.
The Relays can be wire-tied below the dash, above the fuse box; as all of the wires that you will need are already there (including the fog +; but you would be better off splicing that wire at the fog lights in front of the car.)
With the relays; depending on which ones you get; you will use the Normally Open, or N/O post.
Remember, the wires coming from the relays will be ground when the respective blinkers are on.
One other note- where the wires come out of the COMBINATION LIGHT SWITCH; do NOT cut them... I know it shows them cut in the diagram... just splice into them.
Not really- The Hazard switch is seperate; and dropped after a diode. wired this way; the fogs won't come on with the hazards; only with the turn signal switch.
anyway, don't the GRN/BLU and GRN/YEL lines go straight to the turn signals? if so, wouldn't that make the corner fogs blink with the indicators?
No, the GRN/BLU and GRN/YEL lines carry +12VDC, while the respective blinker is engaged. they are the lines that come directly from the blinker switch on the left of the steering column. The "pulse" comes from the relay that their connected to.

ahhh that's how i thought the blinker was wired. i was pretty positive the switch was wired between the relay and turn signals, hence my original idea for the solution.
so that would make this relay a dual position right? this setup suggests the relay is in between the indicators and switch, so a single position relay would cause both to blink.
regardless, i'd suggest using a chassis ground instead of the flasher relay ground. there are plenty of bolts in that area that would suffice. those lights definitely draw a good few amps. better be safe than sorry.
thanks for the tips though, i learned something myself. i'm a ChemE so i don't really care much for this kind of stuff.
I want to thank you all for your help on this matter, it has definitely opened my eyes to what I need to do. I will say though, that I had no idea until today how widespread across all the various OEM's out there that this option was. And I definitely didn't know it was older than the 5th gen was. For this reason, I put a bid up on the harness that DIZAVE619 mentioned. I really appreciate your keen eye for these small things! If I do win this, it will certainly make my job much easier.
And yes, I will post a video as soon as these items become installed and functional, you can all count on that.
This is similar to how I have my current side markers wired... (middle pic in my sig); excep they flash off when the blinker comes on; so the light "alternates" between the blinker and side marker... I might have to move those wires to my incoming JDM side markers; and pick up a set of side fogs, so I can be just like prepreludesh =)
I never really wanted to put things on my car that didn't have a specific function, and always scoffed at the people who had to do everything JDM, but the more and more I read and learn the more I am getting sucked into this hole that I must get all the JDM parts that I can.
I didn't want to get caught up in the JDMness buttt IIIII juusssstt caaann't hhhhellp iiittttt!!!!!
Civics can show off their JDM all day long, but you NEVER see a JDM Prelude in El Paso or in Ohio (at least the areas I was from). The rareness of it is the most alluring part of owning this car!
I just wish I had bought this piece when I saw it up for sale on Ebay back in the summer

Damn you whoever bought this!!!
i was gonna buy that too but they wanted $150 for the switches on the steering wheel to make it work. even then its horrible to wire.
I know! I think we all saw this piece and wanted it in some way!
I'll tell you the really crazy part, I was gonna buy it and when it came time to mount the windshield squirter, I was going to blend it in with some of those custom vortex generators...
And mold them in and overlay it with another nice coat of black paint so you couldn't see where I attached them. Call me rice, but that would've rocked hardcore tasty abs, washerboard style.
So who's gonna fess up and say they bought this piece so the ass-kicking can begin? I personally think our preludes need a rear wiper after going through some crappy storms where the rain doesn't quite go the right way and the rear windshield is covered. That's why I wanted it.
photobucket is blocked from work.. what is it? lol
I demand that you support my work-surfing habbits!
If your talking about the auto-A/C control; it's already on my JDM-izm to-do list =D as is the rear W/S wiper. Not really for functionality... more to see if I can do it.
Damn, and all this time I was pissed when I saw people who had these posts I really needed to see the pictures of. I was glad to give people my reviews because of it's large amount of informative pictures. Sorry about that Mike.
No, it's a picture of those crazy vortex generators that the Evolution 8 used to have on it's roof in the rear, haha.
And I don't think I'll ever do JDM climate control. The real reason is because I don't have A/C anymore, so there's no point in only getting half the use out of it.
And yeah, the rear wiper is gangsta and all, I'm hoping some day to find one again just like you. I'll see you on the battleground of Ebay, friend
The only reason I want to do JDM Climate Control, is because I want to see if I can pull it off... not really for the functionality... Other than when I was in texas (115 degrees in a black car is bad.), I don't think I've ever actually used my A/C... My car is more of a "hey.. wouldn't it be cool if the car could <insert nifty transformers action here>" car... I just like trying different stuff- kind of like my Yukon... I squeezed an engine/transmission in that thing that bearly cleared the front axles of a 22" lift monster truck.. had to shave the hood cross-members to get the hood to close right, rofl
you're gonna run into problems with the USDM ecu. as far as i know the JDM climate control (i think either the single height or the giant one that takes up the entire center console) need a JDM ecu to work properly. you can get a JDM ecu, but i dunno if its simple PNP.
and screw JDM, i need to get my sister to find me a VTi in belgium so i can swap my 25k mi motor into it. while retaining freedom-loving lefthanded drive.
ps: the rear window does indeed suck here in rain.

i want to do the same thing, so i jacked some relays from a junkyard. this is what i came up with how to do it. similar to yours? what's your take?
they're called cornering lights or intersection lights in japan. they're also called cornering lights here in the US. Honda made these for the Accord 94-97.
yeah they're called intersection lights and they are pretty big with CB7's (90-93 accords, what i used to have). this is the wiring diagram on CB7tuner.com
alright. I did the intersection lights on r1emperors car this week. I had a hard time finding a topic that explained every thing I needed to know. in this is the diagram you will see how to wire up any intersection lights if you are using an OEM honda intersection relay, but dont have the rest of the harness
That's a parking pole. It retracts and rises up when you're trying to park. It'll tell you where the front of the car is if you're parking next to a pole, other car, etc.
The device is probably pretty useful in Japan where the Prelude is one of the larger cars sold over there and it's pretty crowded everywhere you go.
Some options I wish we had here (parking sensors, red interior...), and some that seem kinda useless (weird blue seats, prelude side decal, pillow...) in that catalog. What's the option on the second from top prelude on the left side of page 1? Or the one in the top row of interior to the left of the ashtray?
if on page 1 you're talking about the dark blue lude, i think it's just a standard spoiler. if you're referring to the green lude under it, it's the normal spoiler with the raised corners that light up like a bumper pole for parking.
the thing to the left of the ash tray looks like some kind of c pillar bar? no clue either, i was looking at that too.
i think they just light up whatever color the cap on them is, i usually see it as a gray'ish tan color like in that pic. never saw a green one like the pic.
ooh rear sun visor!! i've seen it once now that u mention it. a lot of newer cars have it over here, wonder if we can just ghetto rig it into our ludes
