Hello. My name is ***** ***** I am happy to assist you today. Give me just a moment to review your post, and I'll be right back with the help you need.
Shorting the PCM is a possiablity but before you consider replacing any parts let clear the codes and see which ones return. To clear the codes, remove the negative battery cable for a few minutes and then reconnect it and run the engine and lets see which ones return. Post back with the results and we can work from there.
When you made your repair did you separate the wire and tape them up individually?
The codes P0108 and P0406 indicate you have a problem with the EGR control module and the code P0442 indicates a problem with the Evaporative Emissions (EVAP) Canister Vent Solenoid/Valve. It is very possible the shorted wires caused these two to fail. In order to determine if in fact that is the case you are going to need to do some test. Are you able to do this ?
Okay give me a moment to put them together for you.

This testing requires access to a ful scan tool and reading the data stream. The only other way would be with a volt meter and probing the wires.
It not to difficult but reading the data stream is much more effective if possible.
It should be , its shows on mine. It may be a problem with your scan tool.
Your 2007 has what is called an EGR Module. See it in the link below.https://dl.dropboxusercontent.com/u/104923897/EGR%20module%20System%20Sept%208.pdf
