I have a set of factory HID headlights taken off a wrecked 04 CTS, would they be a direct replacement on my 05 CTS with regular headlights? The HID lights have the ballasts and everything, do they just plug right up after I remove the stock headlight housings?
The plug should fit. However you may have to test the wires to make sure they power up the correct bulb.
I have an 06 with factory HID. A few years ago I got into a head on and lost the drivers light. I purchased my own factory HID housing. And the auto body shop had to re wire it. I don't know if it was from a different model year or what not.
if you own a service manual on CD (ebay is your friend) it shows that the pin outs for the HID vs the non-HID is different. also the headlight retainer in an HID equipped car is different because it takes a different bulb (D1S) instead of regular 9006. you cannot put a D1S bulb in a 9006 base. the only true way for you to see this is to look at the connectors on the headlamp housings, I believe the HID version has an extra pin. I'm trying to convert my non-HID car to HID and am finding this difficult
