Fitting DRLs

[Blueriver]

Hi all,

I've bought a set of drls to fit and I need to find an ignition switchable feed to wire them too under the bonnet. (is 220d 2007)

Does anyone know where I can wire it too? Thanks

Just use a multimeter to check which fuses are dead with ignition off and live when it's switched on, then use a piggy-back fuse connector on it.

Did you get the relays in with the DRLs or did you have to buy them separately?

Was hoping someone had already done this and knew. Just to save me time. Why would they need a relay? I'm sure the ones I fitted to my last car didn't have one.

Because they must automatically go off when you switch on either the side/tail lights or the headlights, so a couple of relays is the way to do it, just like this guy did here:

You can buy a DRL wiring harness with all the necessary relays ;)

Now I never knew that! Takes a bit of the fun out of it though doesn't it? When you figure things out for yourself and make a nice neat job of it, you've got a sense of achievement at the end of the job rather than just working Lego-like and putting things together

Herbs @Herbie, Simon wasn't aware of the DRL switching requirements, then maybe an off the shelf harness would be more suitable?

They aren't expensive either, example harness https://www.carbuildersolutions.com/de/automatic-daytime-running-lights-wiring-kit

Simon @Blueriver, as for a switched live feed, something like the accessories fuse would be a good tap'g point but these are now often located within the cabin/footwell fuse board.  From the engine bay I'd be reluctant to tap into something like the fuel pump or similar component that is critical to the cars running.  If necessary then running a switched feed from the cabin shouldn't be too much hassle.

Let us know how you get on.

Good point Lee, you may well be right there.

Thanks for the help guys. I've ordered a harness/relay with all the necessary connections on it. I'm hoping to fit them properly next week. I have a set that have the running indicators in them. It's a rubber strip that should fit really neatly below the light unit between the bumper.

I'm going to multi meter it up today. Has anyone got a list of which fuse is for what. (I really should get a Haynes manual)

Will be good if you can let us all know how you get on with the install - some pictures maybe?

I tried to install and managed to break the LED strip 😕, so I have to order another. I will post as I setup and fit the new ones.
