I was at work, had to break off and did not want to leave post incomplete. Here is ebay link with many pics.
2013 2014 2015 Chevrolet Malibu Left Driver Side Headlight HID Xenon | eBay
Looking at schematics, the HID is both low and high beam. An internal shutter closes for low beam. The external socket towards grill from HID is DRL.
With Halogen, the BCM supplies low voltage to low beam for DRL and higher voltage for low beam. The BCM closes relay in underhood fuse/relay box which triggers high beam.
With HID, DRL is like Halogen wired direct from BCM. Low beam HID is powered by relay in underhood fuse/relay box. High beam relay activates shutter solenoid for high beam.
