40 Ford trunk wire routing

[Kube]

I dont need the clips..wire from handle base is attached to license plate wire that runs along trunk lid clips to hinge and goes down a few more inches. I need to get the wire from there to the corner of frame where i have tail lights hooked in already. Not only that wire but where does wire go through at to reach corner of frame. If this wasnt mostly original i woukd just run any scrap wire i had here but i want it done correctly

I thought I'd answered your routing question in my previous post.
The wire (cloth covered - black) can be purchased from most of the major parts suppliers for these old Fords.
The harness that runs to the rear of the car - along the frame, crosses over before the fuel tank in 1939. In 1940 it ran all the way back and crossed over at the rearmost cross member.
Does your harness run all the way back like a 1940 Ford? If so, that may be what is confusing you.
