Anyone Know the Guage Wire the 12V Dust Cover to Ballast is?

    I'm putting in LED headlights on my HID system. A video (ALLA lighting, HID to LED) shows cutting the "12V wires" from the "Dust cover connector to HID ballast."

    I need to know what gauge wires they are. They are black and red. The dealer doesn't know.

    Also, my LED lights have two small wires coming off that I need to splice to those wires. They come with those flat male ends (that slide into a flat with sides rolled up female end) that I don't know what there officially called.

    One's 1/4 and the others 9/16. I can't find any 9/16 in town, so I was thinking of cutting those ends off and putting on other type connections.

    I guess I can figure out a plug or different connector on my own but is there one that is a good to use? I need to be able to unplug it in case I need to replace a light but want a good connection.

    Mostly tho, I need to find the gauge of the black and red wire that comes out from the connection on the dust cover, to the ballast.

    Thank you,

    From the way I understand it you're going to bypass the ballast and use its 12 volt supply line to power your LEDs everything else should stay the same your LED should have a receptacle already on it for the HID plug from the car to snap into so as far as I know there shouldn't be any other butchering of the wiring I thought I mean I don't know what kit you have but the thing about the alla kit is in the ballast bypass .

    Okay I reread your business there You've got the some kind of universal business so you don't even have the connection to the HID receptacle the round thing that your factory bulb plugs to You're going to whack that off no kidding well yeah I guess you are I I don't have to go out and look and see if I can figure out the gauge wires that you need I would say 14 16 You could use 12 to be safe when I just did mine about a week ago the wires everything I saw in there looked pretty conventional as throughout the car nothing jumped out at me as being any kind of gauge bigger than 12 or something like that that certainly no 10 or anything like that That's why that receptacle is there that plugs on the back of the bulb and I think even the wires in that are probably 14 16 gauges that controls turning on the light the bulb exciting the bulb in the old system supplying the power to the LED in the new system but you don't have that receptacle setup so you're going to cut that off I don't know if I would do that I would contact Allah and see if you can get the kit that has the wire hanging off of the assembly for you to plug up into that receptacle that's in the car that's how my LEDs are but I don't know.

    I got the HID to LED conversion kit for the 2007 Prius. It's made for my year.

    Some of the connectors have a hole just the size as the wire. Since I have to order off the internet, they ask for the exact size. Like I said, some of the round part the wire goes into is the exact size,The wrong one won't fit.
    Was hoping not to order, wait, have to reorder because I got the wrong size.

    We have a blizzard and freezing temps this week so I didn't want to wait but order now to have it ready.
    You say, "whacking off wires" It's not a big deal to cut the two wires to completely switch technologies.

    Here is the video of how to switch to LED on a 2007 Prius.

    Need to add that I'm not using the blue things. Heard to much bad about them. I'm cutting the red and black 12V wires. My lights have spade wires on them and want to put spade connector on the red and black wires.

    I read the reviews and one person has the same problem of the connector being smaller. They just cut them and butt connected it.

    I didn't want to cut the wire but maybe that is best. I can't use a normal butt connector because the wires are so much bigger then the little wires coming off the lights.

    Will have to try and see if they make butt conectors that have one size on one side and different size on the other side.

    I've connected big wires into small wires on other cars and the big size made it so the small wires comes out.

    Yes sir I have already done all this and two different HID Toyota Prius they're sitting right out here in my driveway Yes if I want to I can cut my wires and do exactly what you're doing instead I bought another manufacturer's kit that I could still if I wanted to cut the wire that feeds the ballast and run that to my new LEDs for power. The only other difference is the kit that I use has a bulb with a wire coming out of it that has the male portion of the HID bulb connector so the silver thing that goes on the back of your bulb in yours and my car will now click on to that wire that's all It just makes it so I don't have to cut anything unless I really think I want to and at this point I didn't really want to because if I wanted to go back to HID 6K or 4300K bulbs I could just do that. But the LEDs do work very well I didn't cut anything I could have I just elected not to and I did have the light assemblies out of the car flipped over right near where they mount and did everything while I was outside and 65° weather. The wiring under those covers that go to the receptacle that goes to the back of the bulb there's just regular Toyota wiring 1416 gauge I do believe and what you're talking about sticking the wire into is a range it's like a blue connector or a red but it's factory so it may not be either of those colors but what's going to fit into that hole and you're going to squeeze onto is generally 14 to 16 gauge I doubt it's 12 12 is pretty stout wire and none of that is needed at this application I was kind of surprised by this too I was expecting the exciter wire or whatever goes to the bulb to be something but not so much that's just not and I thought the Allah kit uses spade connectors after you make the cuts you know you talking about one was I don't remember what with 9 mm and one was another I don't know about that but usually they're spayed connectors like using stereo hookups and sometimes and other things You could change them to barrel connectors if you wanted to you can make your choice squeeze on whatever you like far as a connector goes.

    I did do the cutting to convert from HID to H4 LED in halogen housings which is a little different than what we're doing here.

    I did mine today. Went really easy. Glad I called support. The instructions, post here at prius chat, the video said to put the LED side out, left and right.
    They did not fit so I called up support and they told me the ones I got had been updated and to put them facing up. They fit that way.

    About the gauge of the wires. The wires coming off the lights where very small. The main 12V wires I thought where a lot bigger then they were. They where so small, if they where any smaller they wouldn't be wires. Kind of surprising. They looked a lot bigger on the video.

    The process went really good. Holly Crap!! These things are so nice! No difference between driving in daylight or night :)

    I will try and post a picture here.

    [​IMG]Anyone know why when we link a photo here it doesn't show up?

    Are yours not the type where you're fitting a plastic piece in the hole where the bulb went clamping the wires down and then you shove in the LED and you can index it anyway you like three and nine six and 12 pretty much anywhere in between I hadn't heard that having the cob elements at 6 and 12 which it sounds like what you're saying normally with most manufacturers there at like 3 and 9:00 If you look carefully you can see them looking through the headlight lens but that's interesting I hadn't heard that about the other kit with the elements going top to bottom from ground to sky or whatever we're saying here?.

    Yes in the video they're saying element placement is it three and nine what's going up and down is the metal bar that holds the cob elements on its side of it but it looks like these are fanless.
