First you must locate the DRL control module. It is a black box about the size of a pack of cigarettes behind the radio. It is clipped to the HVAC duct and has two connectors going into it, one blue and the other black.
The blue connector on the DRL module has eight cavities, but only seven of them are used. Cavity B is empty. I discovered that if that terminal is grounded, your DRLs are disabled. The black wire in cavity A is a ground, so I took the DRL module apart (easy to do, the cover just slips off) and solder-jumpered the A and B terminals on the PCB. This leaves you with no DRLs, you power hatch and handbrake light still works, and it all looks factory. Easy to undo if you want.
Some people have expressed a desire for a switch to select whether you want the DRLs or not. This is very easy to do. All you need to do is put a switch inline with the wire that's jumping cavity A and cavity B, and that's it. You will not need to be concerned with fuses in this situation because you're jumping a ground, not a hot wire.
