DRL LEDs - Wiring them correctly

[BMAN_986]

I want to wire in some LED DRLs to sit inside the front grills. I want to do this right so that they are always on when the car is running except when the hi/low beam is on (then they should be off). I believe this is the legal way to have DRLs wired. It is also the most considerate way to oncoming drivers :-)

It appears I can use the attached 12v relay diagram to do this.

Here comes the hack ...

It seems the easiest place to do this wiring is behind the light switch because everything I need is there. I then just need to run my DRL wires up to the relay.

Alternatively I will have to cut the feed to both headlights somewhere post the switch (and other relays?) and wire them to this relay. I'm also going to have to create a loom off the battery and tap into a live +ve feed somewhere. I hope I explained that right :-)

I don't want to do the fog light hack. In Seattle we need them a fair bit as well as DRLs!

Any thoughts?
