could it be done yes, in theory.
You'll need relays to send power from the DRL to the turn signal bulb, and to have it so the relay cuts the DRL power when the turn signal is activated. Or, the much less headache version of that.
On the left of there page click on Daytime running lights, scroll to the bottom, that module when wired in will allow you to use your turn signals as DRLs, and still function as Turn Signals. Seems like thats your best bet.
Part number DRL-1 Instructions can also be found on the website, looks fairly easy, shouldnt take much moe then an HR to make it look factory. My time may be slightly off as i was a car audio installer for 8 years.
