Switched live under the bonnet . (1 Viewer)

[friar tuck]

Hi.im trying to fit a pair of daytime led's to my 2010 ducato.has anyone done this and if so where did you get a switched live from?
Being led they are very low power but as I understand if I tap into something I may trigger off the can bus warning system.only place I can think of is the cigarette lighter feed but have no clue of the wire colours.
Thanks in advance
The Friar.

Cheap ebay offering ?

Not simply a case of finding a switched live, DRLs should switch OFF when vehicle lights are turned ON.
Easy enough to install a relay though.
DRLs have no beam pattern and simply scatter light.
They are too bright and dazzling for night time use.

.GOV website extract...

General requirements
Legislation and requirements:

DRL activate automatically when the engine is started and remain on unless the headlamps are switched on.

Best location will be the fuse box.
Harder to get to but no problem with canbus system....the fuses should all be outside the canbus system so no I'll effects.
Probe each fuse, ign off, with a multimeter and find the dead ones then ign on and find any which become live.
The light switch will activate and turn OFF a normally closed relay cutting the DRLs when lights turned on.

Try the lights on a battery first.
I bought a pair (eBay) which were barely visible at night....in the bin they went.

Many thanks.tried the lights really quite bright.im assuming just triggering the relay which doesn't take much can be done by tapping in to a headlight feed ?

Got the fusbox lid off then lifted out the whole fuse block to look under neath.gulp... it's all very neat with multi plugs hiding all the wiring..to complex for me I think don't want to end up with a mh that won't run.

I bought and fitted one of the "proper" kits (okay I've got too much money!) and it was a doddle.

However if it helps, the power supply came off a fuse (an adapter was supplied) in the under-bonnet fusebox. The feed for the headlight cut-out came from the nearside headlight dipped beam circuit. I had to take the headlight out but it was only 3 or 4 bolts and the connector. This was so the DRLs would go off when dipped beam was selected.

As an aside, just come back from Scandinavia where the law says you have to have headlights on all the time. However this did not seem to apply to vehicles with DRLs.

So was the adapter something which plugged into the fuse location and then the fuse piggyback ed on it?

 

[pappajohn]

This is one adaptor, simply replaces the existing fuse which is then plugged into the adaptor and protects the original circuit.
A second fuse then protects the trailing wire which feeds the accessory.
