Need a little help...

[Hart_Rod]

I'm trying to wire up my cargo light that was converted to a third brake light. I mounted it to the hatch not problem. However I am having a problem going through the header panel that the hatch is attached through. I thought I could snake it through the where they hinge bolts up, but that turned out to be a closed in pocket. I even drilled through the pocket, but that was a dead end also. If you look at a the third picture with the yellow arrow there is a factory bolt in the bend of the header panel. Can someone try to snake a wire up through there to the roof? I would do it myself, but I welded it up before we did the paint work, . If there is access through there, I will drill it back out, but I don't want to make any holes unless I know for sure I can get a wire up to the roof. Thanks in advance.
