Anytime Foglight mod explained electrical (diagrams)

Did this one yesterday! Thanks for posting jive!!!

 

I used the Caribe makaira's method listed at the beginning along with some added tips from Jasonleblond. Not as hard as it looks and very clean. No splice, just move one wire.

 

Congrats! Looks great!

 

im doing this tomorrow... idk why anyone would buy a bright box when you can do this for 1/16th the cost...

 

Which of these methods doesn't cause the fogs to come on (for only a few seconds) a few hours after the vehicle is switched off?

I've had this done for over a year now, and I've never noticed them come on on their own. I think I may have read on here sometime back that some were tapping into the wrong green wire.

 

^^^correct, I did it that way with my own twist and have never had the lights come on either.

 

EDITED POST.

Caribe's method does this. Because of the EFI circuit. See below.

Years ago when this mod was first being done, modders were tapping into the emissions circuit. Well it turns out that the emissions system initiates a system check 4-5 hours after the truck has turned off to check for leaks in the fuel system or something. Read about it in your owners manual.

Use the splice method or Jivewalkers to avoid the EFI circuit.

 

well it wasnt my best work but i got the fog light any time mod done

 

But people have reported this happening with Caribe's method.

 

I am no too confident with electrical shtuff so I figured I would ask before I give this a try. I have aftermarket fogs. How do I "any-time" them? Right now they are tapped into the parking lights.. would I just run that wire to the fuse box and blade connect it?

 

I was wrong. You are right. Carbie's method does in fact tap into the EFI circuit. I just found that out. I updated the 1st post in this thread to warn people of that. The problem with this is that the EFI circuit does an emissions leak test about 4 hours after the truck is turned off. This of course has the unintended side effect of making the fogs come on at night for most people. Some will tell you if you do this to switch off the fog light using the in cab switch each time you turn off your truck. That is one possible solution.

I personally don't like the idea of tapping into the EFI circuit at all. I am (one day) going to use Jivewalker's method for the spade connector. He sent me a wire a long time ago and I need to find it, and reverse my splice.

Thanks for letting me know.

 

Bent tab works great for me, and any future electrical problems will only take 1/1000th of the time to troubleshoot since the mod is obvious, clean, and will take me about 5 seconds to reverse.

 

Unless I am looking at the wrong harnesses, I cannot find a solid green (ignition) wire on my 07 Std. Cab 2.7 PreRunner. I do see a green wire with a stripe, but it is not a light green, and it does have the stripe. Any ideas? Thanks in advance.

 

Is there a certain guage wire I should use for this mod? I'm looking to use jivewalker's method on this.

 

I believe the wire I used was 18 or 20. You could probably look at the wires that share the harness and stick with a similar gauge. I'll check it later on and re-post if you haven't figured it out by then.

 

Your method is superior in many ways. And you are a master of all things electrical, wiring diagrams included--as far as I am concerned. But for some, like myself, can't tolerate the fogs coming on after the truck is turned off. I spend many nights in the backcountry and it would be at the very least rude if I forgot to turn the fog switch off and at most dangerous depending on my location.

Today I found the wire you sent me! Going to install it this coming weekend if I don't do it sooner. I'm excited to finally fix it up and remove the splice.

 

did the foglight mod. It was quick and easy. love it.

I do have a question. If I decided I didnt want the lights on with the switch, rather on and off with the running lights, where would the hook up from the relay go then?

Meaning I like it when the lights go off with the door being opened. I want to have fogs when I want them;
on with running lights
on with low beams
and on with high beams

but I dont really like them on without running lights. Plus like I said, I like the open the door and lights go out feature.

I looked on wiring diagrams but it starts looking super foreign language to me after a while. Is there a place in the fuse box that I can jump to to get to the running lights on position to trigger my relay?

 

If you did the bent relay tab version and you leave the fog switch in the on position, then the fogs should will go on and off with the ignition. Are you saying that you want them to stay on until the door opens with the ignition off like the headlights? This would only gain you that time from when you turn the ignition off until you open the door? With this mod you should be able to run the foglights "anytime" other than iginition off. You would have to find something that is +12v regardless of ignition if that is what you want. Not sure what is "always on", would have to probe with a tester. Good luck!

 

I tried doing the mod, and it does work, however, my check engine light is on, and I slowly put everything back to normal, and the thing that is causing my check engine light to stay on is due to the bent foglight relay, please advise, thanks and happy new year!
