DRL -> Headlights Wiring Schematics (pics)

[NSXTC]

Below are two schematics to wire your DRLs:

The first one uses your parking lights to activate the DRLs.

The second one uses a switch that you install inside the vehicle.

First, some relay basics:
There are two basic circuits in a relay. One circuit turns the relay on and off; the other circuit passes current through the relay once it's turned on. The wire going to terminal 86 is the wire that activates the relay. When terminal 86 has power applied to it, the power goes through the relay to terminal 85 to ground. This turns the relay on. This allows high current (power)to go from terminal 30 to terminal 87, which puts power to the DRLs.

Basically, all you have to do is splice into one of the existing parking light's positive lead to the 86 post on the relay. Next splice both positive leads from the DRLs and combine into one wire of similar thickness. Take this combined wire and plug it into the 87 post on the relay. The rest should be self explainatory.
