Your location says CA, is that Canada or California? I havn't seen a P5 in Cali with DRL but I've heard of them in Canada. I'm guessing that the DRLs are the same as my parking lights. I'm sure you can put in a relay so that the power to the DRLs is on normally open, then power the relay by the parking light switch. Then when you turn on at least the parking lights, the relay will be powered and switch, then to DRLs will now be parking lights. Sorry I don't know the wire colors. Or, an easier way, but don't know if it's possible on a DRL equiped P5. Just cut the wire going to all the lights, and run wires to the lights off the headlight switch. Again, I don't know the wire colors. I would go with the relay system, it would be safer and actually easier now that I think about it.
