Guy the factory DRL wire is the Light Grey located on pin 10 of the harness, which is right below the Yellow wire.
The yellow wire, which is pin 9, is for the Parking lights.
Here is the reason why we went with the ignition wire and not the DRL wire (Light grey)
1. The factory DRL only come ON when there is enough
ambient light outside to keep the headlight OFF, as long as you have the switch on your stack set to AUTO.
2. Once the sensor detects that there is not enough light outside it will turn ON the headlights (if you have the stack on AUTO). This will cut the 12v signal going to the factory DRL (light grey wire) and switch it to the parking lights (yellow wire)
3. By switching off the 12v signal from the light grey wire the CK71 DRL will turn off as well.
By using the ignition signal we guarantee the CK71 DRL will remain ON during all situations.
Better pics and a video later.

Add another one to the list. Easy DIY install. Really makes the front end pop at night. Thanks again Chris71
Didn't have time to edit. Had troubles with my floodlights.
