I used some of these to be able to disconnect the DRL.
Electrical Waterproof Connectors Set 1 2 3 4 5 6 Pin Way Superseal Pair Car Boat | eBay
The NISMO lights have a connector on all ready but i couldnt source the female end to use on the loom I created. So i removed the OEM connector and used the ones linked above.
Which DRL do you have?
