I found an answer to my DRL question (regarding rewriting my pigtail) from the original CK71 thread.
The DRLs are powered by two separate wires depending on whether or not the headlights are on.
There’s a separate DRL only wire which is Light Grey for daytime use. The Yellow parking light wire takes over when the headlights turn on leaving the Light Grey wire without power.
That’s why the CK71 instructions opt for the IGN wire which is always powered.
So, the Shark Racing PNP harness blue pigtail is coming off the Yellow wire (GT/GT1, maybe the same for GT2).

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.
