Fog lights, on with High Beams?

Done.
Took one cut, two splices, a scratched elbow, cramp in lower right rib cage, and some tape. Will clean up later with solder and heat shrink tubing but here's the pics. I know they suck. (1.jpg) with low beam and fog, the other (2.jpg)with high beam and fog.
pretty easy acutally.

Sorry it's taken me so long to get back to this thread. Everybody in the family has been sick, I decided to swap out the factory speakers, ordered Predator, . . . , just busy. Anyway, here's a writeup on the mod and I will get pictures this weekend, maybe. I'll probably wind up getting stuck at work all weekend so it may be next weekend before I can crawl under there again.
1. When you turn the fog switch on, it sends a ground signal to the Smart Junction Box (SJB) over a wire (Orange with Light Green Stripe).
2. The SJB then sends a ground signal out to the fog light relay (Dark Blue with White stripe).
3. The relay then sends +12v to the fog lights and you get light.
Now, the same SJB does about the same thing with the other lights including the brights or high beams. It knows that when the high beam signal somes in, it turns off the fog lights by stopping the ground on the Dark Blue/White stripe wire. What we have to do is take the SJB out of the equation. Basically make the fogs work on the switch and only the switch. What I did was just cut the Blue/White Stripe wire coming out of the box, and then connected the end that goes to the Fog Light Relay to the Orange/Light Green wire coming from the switch. Now when the switch is on, a ground signal is sent directly to the blue/white stripe wire, bypassing the SJB.
This was all done on the passenger side of the vehichle, just behind the kick panel is the SJB. The blue plug on the front contains the Orange/Light Green Stripe wire. The Blue/White Stripe wire is a little more difficult. It plugs onto the back of the SJB but I found it in the bundle of wires going though the firewall a little forward of the SJB. I unwrapped the wire bundle, dug out the thin blue wire and cut. I figured that if I made a mistake, well, I tried really hard not too.
There are a few catches that I haven't looked much into yet:
I think the SJB will turn off the headlights if you leave them on for a long time. Since we bypassed the SJB on the way to the fog lights, it won't be able to turn them off in that event. It should still turn off the headlights, just not the fog lights. So don't leave your fogs on overnight expecting the car to take care of it, it can't now.
Also, WEBEPRODUCTS mentioned that the switch might not be able to handle the current going through the switch and directly to the fogs with out going through the SJB. I honestly don't know, yet. I need to test the current draw over the wires but they were both small gauge, both plug into the "low current bus" on the SJB. I think it's safe but better to test it out first.
Legality is probably an issue. Most states have some sort of law against this but some states have laws that are against the original setup too. I found one state, I think it was Oregon, that seems that the fogs can't be on unless they are dimmed with the brights. So it sounds like they should only work when the brights are on.
And I would even argue that the High + Fogs are still less light then you can buy from an HID kit, so how is that legal?
I'll take some more pics as soon as I have the time.
Those pics I took earlier really don't do it justice. Just the camera taking lousy pictures. No, I don't have smoked covers but you can tell that the fogs stay on with low and high beams. Lastly, I've been driving like this for a few weeks off and on and haven't noticed any problems.

PS, don't blame me if your car burns up, you burn up, or your rap-sheet burns up, I'm suggesting you don't do this. But my car looks cool with it.

Mike,
Thanks for the info. I just installed the Saleen HID kit. I will be doing a Cervini's front bumper with new fogs. I'm going to wait and see what the fogs add to the headlights before I do any modding. I'm sure your writeup and photos will come in handy.

...diging up this old thread...
I'm thinking about doing this mod. Has anyone with an '07 tried it? Also, for anyone who did this - were there any problems?? Was the switch able to handle the current over time??

I've had no problem with switch at all.
Ironically, I'm looking through the forums for some info on grilles since I ran into a deer! I didn't have the fogs on at the time but I normally do drive with them on at night when going home. Lots of deer out at night. This time, a buck got me first thing in the morning. Nailed it doing 70 on cruise.
As far as the lights go, no problems at all after two years.

I am having no trouble with my much different conversion.
All I did was switch the 2 contacts in the headlamp conector in the harness.
My SBJ just thinks my highs are lows and vice versa.
I now have a relay for low beams and an indicator in the dash (instead of highs).
The headlight current draw is not different enough to cause a problem.
The driving lights use almost the same current as the old hazy fogs did.

I finally had some time last night to try this - and yep - it works!! ...now, my fogs stay on even when the high beams are turned on. THANKS!!!
