I've completed the installation of the CSL headers and euro section 1. The job was done exactly as described by Jumbosock (which was very well described). I also purchased and installed new o2 sensors for pre and post cats.
I did nothing else and am satisfied that the job was done correctly. The battery was disconnected during the process, on a trickle charger and is fully charged.
Tried to start the car and I get clicks from the starter, nothing else. My Peake code reader indicates that there are no faults. I did go ahead and clear/reset it. Again, nothing but clicks from the starter.
I must have bumped or did something and would appreciate any thoughts.

EDIT: My error. False alarm. Just corrected some corrosion on the negative terminal. A bit of sandpaper and she is purring perfectly. Thanks to all.
