In case anyone wants to know, it doesn't go throught the middle.
I took the shelving off of the back of the door and used the stud finder along the "great stuff" like foam. With the freezer plugged in, and using the stud finder, it seems that the electrical lines run up the side and across the upper 1/4 of the freezer door.
Might post pics later. Will have to have the links to my site. Depends on what the brew tell me to do...
Woot, woot!!! I'm just happy that I didnt hit the lines and the new kegerator will be in service soon.
