Hi everyone

I'm a newbie so this is my first post.

I've have just purchased some Osram DRL & I'm hoping to fit then to my 09 plate Mito, it seems pretty straight forward but I'm nervous about the wiring side.... The Drl's come with an auto dim feature which is cool as I still want them on when the headlights are on, my question to you guys is would I wire them up to the sidelight or headlights, as you know the mito has side lights that are always on so I'm guessing this is a no no, I don't want the DRLs on full all of the time.

Any advice from someone who has fitted them would be greatly appreciated


Thanks

Jason

The lights on the Mito that you're referring to function as both DRL and sidelights - they have dual filament bulbs. The bright filament lights up to function as DRL when the ignition is on and the headlamps are off and then when you turn on headlamps they switch to the dimmer filament to function as sidelights. You can turn off the DRL part of this through the menus.

Doesn't help you with your wiring, but I thought it worth clearing up!

Hi, yeah I appreciate they are dual type bulbs, that's kind of why I'm wary about wiring my DRLs into the sidelight, I need my Drl's to either go off or dim when the headlights are on

A much (much!) easier solution is to swap the DRL bulbs for Polargs. They offer a very white light, and look much nicer than the standard bulbs.

As long as you can get some which are well made and a good fit! There's a lot of bulbs (esp. on ebay/amazon) labelled as polargs which are copies it seems (and don't come in branded packaging). I ordered some off ebay from a seller with a good rep which were a poor fit, in fact one was such a poor fit it fell out forward into the light unit and I had to use a magnet to fish it out. I've read of a number of Alfa and Vauxhall owners who've had similar issues with M13 "polarg" bulbs. No idea if genuine polargs are a better fit. If anyone does know of a source of them where they are a good fit in the holder and won't fall out that would be useful :).

It's £80 worth of DRLs so id like to install them if I can, I just need them to go off when the headlights are on and on again when I switch them off

I hope not, Osram told me their kits don't interfere with the Canbus

I'd guess should be two feeds to the DRL/Sidelight bulbs - one for the DRL and one for the sidelights. I'd think, based on the way they behave, that the power to the sidelights would be on only when the headlights are on (dipped or main). In any case you should (as I mentioned earlier) be able to turn off the mito's DRL facility anyway from the menu, in which case you can be sure power to the sidelights will only be there when the headlights are on. I presume the Osram kit uses that to activate the dimming rather than to actually power anything? And you'd be using an ignition switched feed to actually power them?

Osram have just informed me that my particular kit doesn't have a dimming function, they go on with ignition and off when headlights are on. The lights are powered by the battery directly

OK , ive just spent an hour fitting the DRLs , but ive hit a bit of a snag , i have connected the red wire to the + & black wire to the - of the battery , no i am left with a Green & Orange wire from the control box , at this point the lights have not come on , im assuming this is because i still need to connect to the side light? my snag is that the side light has 3 red wires on it , which one do i connect my orange or green wire to ?

Sorry im a complete novice and the Osram PX-4 instructions are rubbish

The px-4 instructions show that the orange wire goes to CL15 and the explanatory text says:

"The control box is connected to the vehicle battery and to the plus terminal on the ignition (terminal 15) of the vehicle. The daylight
driving lights come on immediately as soon as the ignition is turned on. As soon as the vehicle is switched off, the daylight driving lights go out The location of terminal 15 / ignition plus terminal varies according to the vehicle. Further information concerning the location of terminal 15 on the vehicle can be provided by your specialist workshop."

They're not coming on because you need to wire the orange wire to a positive terminal that's switched by the ignition. The green wire is the one that needs to connect to the sidelights and that's presumably used to turn off the DRL when the sidelights are on. Can't help you with the nearest location of an ignition plus terminal on the mito to where you're fitting the DRL, and also can't help you with which one to tap out of the 3 wires in the Mito's DRL/Sidelight (I imagine there are 3 wires as one will be positive for the DRL, one will be positive for the sidelight, and one will be negative). You need someone who knows a bit about mito electrics to help you out or a general auto electrician.

Thanks mate i appreciate your input on this , i can use a multi metre to determine which of the 3 side light wires is a live feed when the ignition is on , i assume the terminal 15 ignition terminal is one of the fuses in the fuse box?

the good news is they look great on the MITO , i just need them to come on now lol

You need to determine which of the 3 side light wires is lived feed when the headlamps + sidelights are on (basically ignition on, headlights on) as that's the one you want to connect green to. The Osram DRL will use a live feed on that wire to signal it should turn the DRL *off* when the headlamps are on.

I don't have much knowledge about car electrics terminology, but I think terminal 15 just means the part of the electrical system which is switched live by putting the ignition on:

The orange wire is very short on the kit , so im guessing it must me fitted somewhere close to the battery . i will connect the green wire up to the sidelight tomorrow & see what happens
