To get DRL working for CHL you need to splice DRL wires to the wires for the front fog-lights.
Remove the driver bolster under steering wheel to gain access to the BCM.
Splice it directly at the wiring harness from the 23 pin connector located on Body Control Module (BCM) using snap lock (scotch locks) wire connectors( if one port on snap lock is partially blanked then just use a 3mm drill bit to drill it out so you can have the full fog wire running through it and the DRL wire by its side.
Please check for 16 & 18 to be the right pins for DRL Bulbs before splicing, You can check by using a test light and checking for presence of voltage whilst operating the DRL switch on/off.
You need to connect Pin 16 to Pin 19 (next to each other in connector housing) and Pin 18 to Pin 21 (next to each other in connector housing) there is no need to cut any wires just use the snap lock connectors 2 are required.

18: DRL Left
19: Fog right
21: Fog left
Then enjoy Coming Home Lights
