Re: DRL Still Works After Removing DRL fuse
The DRL's always have power from the ECU. When you turn on the headlight switch it gives them a solid (-) neg ground potential and they get brighter.
So, your xenon's are getting partial power in DRL mode. Not sure if that is a good thing for longevity of the lights.
If you want to disable the DRL's, behind the drivers headlight is a grey connector to the DRL resistor (resistance to chassis ground) If you disconnect that, your DRL circuit will be disabled. The DRL fuse you removed may be better reinserted because it probably goes to the DRL relay that connects the headlights to the solid chassis ground. ( I am just going from memory without looking at the schematics)
With that fuse removed, you may be taxing you new lights with or without the headlight switch "on" because that relay never triggers to switch your circuit to the solid chassis ground, and continues to direct your lights through the resistor.
Reinstall the fuse and disconnect that resistor behind the drivers headlight.
I undid the plug and just slightly mated the connector back together to stop an excess of water and road grime from FOD out the open connectors.
I thought at one time I would try to get both connectors (male and female) and use them to wire in a switch so I have in ****pit choices, while keeping the connectors sealed against moisture.

Oh, What a feeling...
