What happens when you try to release the trunk?
The trunk open from the back up. You may just have a fuse problem but thats where the problem lies if it will not open, I take it yours dose not have a rear lock for the key?
The only other way I can think of to access the truck if the lid will not open would be to remove the back seat and see if you can access the larch from there and get it to release.
Is there some why that you can make up something to reach in and get a hold of it?
So what part is not working, is it the trunk latch?
Have you connected a a capable scanner and check for trouble codes?
These two code are lean engine codes and will have no affect on the trunk. In order to retrieve codes from the Body control module you will need a full scan tool. A code reader will not work.
The loose wire may be related but I would start with getting the scan done and see what fault codes are setting. Doing so will help us determine where to start.
The first code is the one you are going to need to address first. See the pinpoint steps in the link below. Copy and paste the link to your browser to open and view them.https://dl.dropboxusercontent.com/u/104923897/B3669%20Jun%202.pdf
