The Only Fog Light Thread You Should Ever Post In

[rajin929]

looking forward to the outcome of this!

I'm thinking of using the OEM switch and the Hella Fog Light kit (if they are still available)....the wiring harness you guys are working on will help me connect the two LOL

[timot_one]

Just use the OEM harness and you can convert it to whatever you need to power the bulbs in the hella kit if they're not H11's.

Ordered my set of OEM fogs today. I wish our cars were pre-wired like most top-of-the-line trim models for other makes like Nissan and Toyota. Oh well at least I have a fun project I suppose.

^it's really not that difficult of an install.. especially with an OEM kit. just don't forget the fuse.

[Philly Steve]

I ended up chopping up pieces from the OEM harness and an E-bay harness to create my custom harness.

OEM Parts:

Fog Light Switch
Blue 6-pin Male connector
Gray 2-pin Male connector

eBay parts:

H11 Male connectors
30A 4-Pin Relay
Connector for Fog light Positive(+) from relay to H11 connectors


How I wired the switch (keep in mind I used an 06-07 kit but others should be similar)
Blue (ground)
Green (Positive when Fog Light Switch "ON")
Red/Black (Positive when Ignition switch "ON" - wired to Red/Black wire on Blue 6-pin connector)
Red (Positive when parking lights "ON")
There is another wire Red/Black wire looped to another pin. Leave it alone.

How I wired the Relay:
30 - To Green wire on Switch connector
87 - To Yellow/Black wire in Blue 6-Pin connector
86 - To Fog Light H11 Harness
85 - To Ground

Will try to post pics later on but unfortunately it's already installed. lol

Sounds like a great project be sure to post a diagram for the diy

[murd0x]

dam philly you should come down here and help me with my fog harness when your done with this. or maybe i go to you....

[Philly Steve]

I did finish this a while ago. I could do it again I just don't have actual pictures. Will make a diagram one day though. I swear.

I was thinking of removing the cylinder inside the fog lamp, the one around the bulb, to make it more clean, like the high beam. I was wondering if it will create a wider spectrum or the light just disappear in the road.

Any thoughts?

[CrackerTeg]

The beam won't focus properly and it'll just be a glaring nasty ball of light. That cylinder is to have the light reflect off the rear of the housing only. Try projecting an incandescent bulb's light similar to what you want to do and you'll see what it looks like, then make a "cap" for the same rig and compare.

[timot_one]

Aftermarket fog lights don't come with that "cylinder".

[CrackerTeg]

Now that you mention that Tim, I remembered my fogs don't but the bulbs have that "cylinder" already on them ie. the tip coated. Guess I forgot about that.

[timot_one]

All H11 bulbs have that little cap.

And finally a blurry comparison between the two bulbs.
