    4 male, 4 female blade connectors, crimper and wire... thats it. Get standard size 1/4in wide blade connectors and for the ground (green wire in my original post) simply take a pair of dikes to chop down the width of the male blade connector.

    Yeah... requires soldering, keeps low beams on with high beams which might result in burning the housings as thats 115 watts of heat per side...your way just so happens to let you run high beams and fogs by product of the low beams being on all the time.

    Also if you really wanted the fogs to only be able to come on with high beam or low beam and no other time, diodes should be used to properly fire the respective relays.

    It doesn't 'require' soldering but ideally you would. One can easily wrap a wire around which works just as good if you're not OCD like me with electrical connections. As for melting headlight housing's... it's really not a concern. I was more concerned with the electrical aspect of running all HIDs at startup but after a year everything has tested just fine. FYI, the housings are engineered to handle heat much hotter than a couple headlight bulbs can throw at them.

    Thread jack? All I did as give yet another option for users to consider. It's not like anyone is making money on people's decision or something. Not everything is about lifting your leg & peeing on it to claim it in the intrawebs. I'm pretty sure the OP understands that but your excitement on the topic is appreciated.

    I was just checking my relay box yesterday to do this, but I don't have the correct size terminal blades yet.

    One thing I noticed was I am missing a relay in that box. Under the relaybox cover it says an 'Air Pump Heater' relay goes there, but I don't have one.

    It looks just like the fog relay in the OP's pics. Anyone else missing this? Is it a Canadian cold air thing?

    yeah no its definitely an interesting option and like you stated it should be soldered. It definitely sucks that the way toyota wired it that the high and low beams go through the same relay... if they were separate relays you could do it much better with 2 diodes to fire the separate circuits at once.

    And definitely not taken as a thread jack at all.


    do you have the exhaust air pump cus thats what the relay is for AFIK... located on my truck just aft of the intake tube that goes through the wheel well is the pump... wacky lil thing that pumps fresh air into the exhaust manifolds for a more complete burn in the cats.

    I've been putting off this mod because I didn't like any of the options I had seen…until now. Looks good, I'll definitely be doing it this weekend.

    Aw just trying to have a little fun. Maybe I've been too easily influenced by some of the old crusties on here.

    Both are good options I'm sure, I haven't done either yet, but I have noticed that fog lights on with high beams would probably be a great help to my visibility at night.

    That is the main reason I did the mod in the first place.

    Just did it today. Straightforward and worked out without problem so far.

    Thanks OP!

    Doing a little digging in the wiring diagrams for our taco's.... if i have read this right.

    If you wanted the option of the fog lights ONLY turning on with high or low beams so when turning to DRL / Parking / Full off on the control stick the fogs would TURN OFF it seems very easy as well. This way you could leave the foglight switch on, and when you turned headlights off they would go off as well.

    Simply move the brown wire in my original post to either, pin 3 of the HEAD relay, or pins 1 or 3 of the DIM relay. As all 3 of those points are switched to a 12v hot when the control stalk is turned to headlights regardless of high or low beam.

    When i get back from a small vacation i might take a look and take some pics of the fuse box and actual locations on my '13 OR and do some actual testing.... try this at your own risk... hell try anything in this thread at your own risk... that should go without saying.

    I just did it too. Works great!!!
    I had a little trouble trimming my connectors to make them thin blade connectors but other than that... this is one of the easiest mods I've ever done.

    So i took the time to actually go and pull the HEAD and DIM relays to test my theory quoted above. The best spot to pull the switched on headlight 12v would be from pin 1 of the DIM relay as it is the closest to the edge of the relay and oriented in a way that makes it easy to bend the male spade connector. The other two locations are doable but you would need to VERY long male spade connector as the blades of the relay are dead center on the relay body.

    So if you wanted your fogs to ONLY come on with high OR low beam and go off when you turned your headlights off this would be the location to put the brown wire in my ORIGINAL POST, And as always all of this is 100% reversible back to stock.

    Did this mod on Saturday. As everyone else has said it is simple and effective. One tip I have is if you would rather not trim the blade connector for the green wire you can use the smaller size (.110 I believe) for that wire only. Thanks OP for a great mod!

    I'm a little confused. I have the small box next to the main box but it doesn't look like yours. 2010 DC TRD Sport BTW....

    OK, The foglight relay is the one directly below the big gray headlight relay. The dimmer relay is the same as the one you posted above. So what it looks like is I need to pull the fog light relay, make the extensions as show in the OP but where is my AC inverter relay? Is that what's in the external box? If so would you suggest it's better to pull the switched power from the Dimm relay?
