I have a 2007 cts with HID, I bought the spec d projectors and an hid kit to still have hid bulbs.

The head lights work fine as I hard wired them the led strip and hight beams do not, it seems as if the stock connector does not quite fit. Has any one done this swap before or know how to get the lights all to work?

Any thing to help trouble shoot please.

Between 2003 and 2007, GM changed something on the harness. Moved a pin or something. Because when my 2006 was involved in a head on crash, the driver's headlight assembly was replaced. I bought it off of eBay, factory HID for factory HID. The shop had to move a pin or two in order for the high and/or low beam to work.

I don't know what pin it was or what not. So you'll have to test them out. Meter each pin while someone else is turning the headlights on/off and high beams on/off.
