Thank you for your instructions. I was able to figure it out by looking at the construction of the vehicle's front and from previous information. I ended up doing the steps you described. I must say though that I have never had to go through so much trouble to replace a headlight assembly. The CTS is an absolutely fantastic car but the headlight access leaves a little something to be desired.
