Re: JDM Foglight Switch Wiring - How to (Mike M)
 

Can someone please explain why a relay is needed?

In order for fog a fog light to work all u need to do is connect the positive to a battery and negative to ground and it lights up. What's the purpose of a 30 amp relay for?

And i just don't understand is this, for fog light power suppoy all u need to do is tap the power from fog onto ur lowbeam p[ower wire and there would be ur power source.

But, overall I would like to know the benefits of using a relay.

Thanks

Re: JDM Foglight Switch Wiring - How to (serenity)
 

A relay is needed, and a 30 amp relay at that, because the switch is not rated at that high of an amperage. If I had to guess I'd say the switch is only good up to maybe 2-3 amps. The Foglights will pull alot more amperage than that, somewhere between 15-30 amps depending on the wattage of the bulb used. Now if you tried to wire it direct and not use a relay you would have a bunch of melted wires and most likely a fried switch.


You could just connect the positive for the light to the low or highbeams but then why have a Foglight at all? Legally you must be able to turn on and off all the lights seperately, as well it is illegal to use your foglights when the weather does not call for it.

Don't take this the wrong way but if you plan on doing any type of electrical work on cars, please read some books about it first, this goes for anyone on here with little knowledge of Car electrical systems.

Re: JDM Foglight Switch Wiring - How to (Mike M)
 

thx for the explanation.

But i would like to ask this:

What i did was I hooked the power supply to the low beam and a switch in between, so i can turn it on and off accordingly. The power wire I used to attach to the low beam is 14 gauge wire. by me using a thicker guage wire wouldn;t it prevent any melts?

and in regards about ur comment about the wire melting and what not i'm assuming that this will be occuring over time and nothing immediatley, correct me if i'm wrong.

But either way I appreciate u explaining the need for the relay it makes much sense to me now, I can understand why my alarm parking lights wire melted/burned out over time when i attached my high beams.

So, in the case of a relay, the whole intention and purpose of it is to prevent any melt downs and burning of wire? along with handling the power load? correct me if i'm wrong.

Again thx for ur explanation https://honda-tech.com/forums/images...es/emsmile.gif

Using a thicker wire than needed will only add unwanted resistance in the circuit. The reason the wires would heat would be because the Switch is not rated at 30 amps. If it is and your not going over the switches amperage then you won't have a problem. Just an FYI I would also Fuse the Switch on the Power wire coming into the headlights.
Also note that you now have your Low Beams (drawing aprox15-20amps), 14g wire running off the low beams harness and a switch adding resistance to the circuit, as well as the Fog lights drawing extra amperage off the <u>Smaller</u> OEM Wires that run power to the Low Beams. If you don't melt the 14g wires or switch you'll probably melt the low beam wire harness, and it won't be fun to fix.

Think of the Relay as an Electronic switch. You have a low amperage power source feeding a manual switch, when switched on it feeds power to the electronic switch in the relay, the relay is now latched and completes the High Amperage circuit (high amperage source to feed power to the fog lights)

Beyond these explanations I'd reccomend getting some books on how electricity works. https://honda-tech.com/forums/images/smilies/embeer.gif

Here it is.
First you will need the plug from a 94-01 Integra's Cruise control switch, Just cut it off the main harness with 4-6" of wire. The colors of the wires will be different than the ones shown here, But the pin locations are the same (I will update this with correct pics at a later time)
These were posted at one time by Glen UKB18C6
http://www.ipsracing.com/tech/foglightdir1.jpg
http://www.ipsracing.com/tech/foglightdir2.jpg

Once you have that all sorted out you will need to run power and ground to the switch for the switches illumination and also for its output.
The (+)Constant, (-)Ground, and (+)Lights on will all be tapped from the Accessory plugs on the fuse box, Use 16 gauge wire to run to the switch and relay, Use Insulated Female Spade terminals crimped onto the wire to plug it into the accessory locations and to the Relay (Unless you have a relay harness).
The relay is a standard 30 or 40 amp relay available at any auto parts or Car Audio store.
Use the following diagram to wire the switch and foglights up.
http://www.ipsracing.com/tech/foglightdir3.jpg

The Blue wire going to the engine bay that passes power to the actual foglights is already in the cars harness, Its a blue wire with Brown connector, wrapped to the closest wiring with blue tape. One end is located under the dash right above the clutch pedal (connect this to the relays output), the other end is in the engine bay on the driver side headlights harness brown connector blue tape (Extend this wire to the foglights power terminal on both headlights.

The foglights will work whenever the parking, low or high beam lights are on and the switch is on.
This will work with any aftermarket foglight kit also.

PS We still have a few JDM Foglight switches on Special &lt;IMG NAME="icon" SRC="http://images.zeroforum.com/smile/emsmile.gif" BORDER="0"&gt; </TD></TR></TABLE>Is that the pic of the cruise control button clip? So basically I would pop off my cruise button run the red yellow stripe to a relay, is the 2 black wires already grounded? Then I cut the 2 other wires and send it to the fuse box switched power.

Re: JDM Foglight Switch Wiring - How to (capcon83)
 

I want to swap my PIAA foglight switch to my Cruise Control switch.
There is 3 wires from my PIAA switch; 1 red (power), 1 black (ground) and 1 white (switch power). Where do these 3 wires go in the Control Control switch?

Re: JDM Foglight Switch Wiring - How to (Mike M)
 

just for everyone's info, the fuse box location is slightly off. The illumination output should go in the 5th slot from the left, rather than the 4th as indicated in the diagram.

1st, 3rd, and 5th slot from the left. It looks like you have the 1 and 3 slot filled.

were talkin about the top row of fuses right ? https://honda-tech.com/forums/images...s/emsmilep.gif

also wat kind of relay did you use ? i used a oem honda relay i snagged out of a car . are the spots marked +/ - or can u just hook it up to which ever one ?

i appreciate your help https://honda-tech.com/forums/images/smilies/emthup.gif

Re: JDM Foglight Switch Wiring - How to (JonnyDanger)
 

no offense man, but the diagram Mike made tells you exactly what you need to do. It tells you what relay, where each wire goes etc.
And I was talking about the empty slots above the fuses (accessory slots), not the top row of fuses.

Re: JDM Foglight Switch Wiring - How to (Mike M)
 

What if you already have cruise control? Is there a shortcut you could take instead of doing all of this? That being because you already have power going to the switch, and having it activated to deliver power.

A couple of things on if you have Cruise control and a JDM Foglight switch.

1) You can install the JDM Fog switch where your dimmer switch is, usually you don't change the lights brightness much so set it and zip tie it under the dash. An alternative would be to make a small mounting panel so that you can reach under the dash to adjust the dimmer.

2) You can use Some of the wires from the Cruise control. You still have to tap the fuse panel for Main power and ground and will have to wire up the relay but you can tap into the Cruise harness for the power into the switch that eventually triggers the relay (The Positive feed when the lights go on) This wire tells the switch when to ilumintae with the other switches when the lights are on and also only allows the relay to trigger when the lights are on. (Basically the only shortcut you have is being able to tap into the cruise harness instead of the fuse panel for that orange wire in my diagram. The other plus is if you dont plan on keeping cruise control you already have a plug for your fog switch, although you have to rewire most of it.)

Re: JDM Foglight Switch Wiring - How to (Mike M)
 

Anybody know what type of bulb the JDM foglight is?

Re: JDM Foglight Switch Wiring - How to (migs)
 

About 90% sure it is an H3 bulb.

Low Beam is D2S for HID or 9006 HB4 for NON HID, High Beam is H1, City light is a 168 bulb.

Re: JDM Foglight Switch Wiring - How to (Mike M)
 

The thing is, I pulled out my cruise control, so I only have the switch and the plug under the hood where it once plugged into the cruise control unit. So I'm planning on mounting the switch in the OEM place where the cruise control once sat anyways.

Under the hood there is four wires coming from the plug. They're orange with black stripe, orange with red stripe, orange with white stripe, and black. Making it a total of four. Is there anyway I could just work from here?

Just follow the diagram Mike made. It's super easy if you just read it carefully and plan out your install.

What's in those slots? The first second and third from the left. Mine are filled also (2000 GS-R). Would I just unplug them and plug the wires in for the fogliht setup?

Can someone post an actual picture, or detailed description on where this blue wire is I'm supposed to use for the foglights. Is it just solid blue or does it have a stripe on it? I can't find it in the engine bay, or under the dash above the clutch pedal. https://honda-tech.com/forums/images/smilies/emsad.gif

One last question, on that diagram of Mike's it shows the red wire going to the fuse box and it says 30 AMP fuse on it. Is that just referring to the amperage of the relay or do I have to mess with a 30 AMP fuse on that wire/something of the sort.

Sorry for all the questions. http://images.honda-tech.com/set1//smile/emcrook.gif

Re: JDM Foglight Switch Wiring - How to (Gatecrasher20AF)
 

you have aftermarket wires in those slots, they are empty stock. That blue wire is not stock either. I'm not sure what accessories you have in your car, but unplugging them those wires would mot likely disable them.
You must use a 30 amp fuse, he's not just saying that for the hell of it.
I'll try and take a pic of my setup.

Re: JDM Foglight Switch Wiring - How to (NWP4LIFE)
 

don't know why the pic got so messed up but you get the idea...
