Sheayo, your stock DRLs are actually the high beam head lights running at a reduced voltage, so you'd want to tie into the DRL circuit to run your LEDs in parallel with the DRLs. So, that being said, you need to determine the operating voltage of your new LED lights. If they are designed to be operated in a range of voltage from, say, 8 - 14 volts, then you are OK. If not, and they are 12 - 16 volt lamps, then you'll need to tie into the DRL circuit between the relay pin out and the DRL resistor, (provided the current draw of the LEDs is minimal - - less than 1 amp or so). If the current draw of the LEDs is too high, install a relay in line with the DRL wire and then tie your LEDs in to a spare, fused accessory circuit (something like that for the cigarette lighter).

If you'd prefer and don't mind having the LEDs on all the time the engine is running, you can simply tie them into an accessory (ignition "on") circuit.
