1937 Roadmaster - Wire bundle from engine compartment rearward on top of frame?

[Mutt's37Buick]

I'm removing the secondary wire harness from my 1937 Roadmaster.

I have all the front lights, horns and electric loose back to the dimmer switch loose.

There is a bundle of wires that runs past the dimer switch along the top of the driver side channel of the frame.

I'm assuming this goes to the tail lights, but I'm having trouble seeing where it routes up to the rear back at the trunk.

Can anyone tell me if this bundle goes to the tail lights?

Can anyone tell me where it passes back up into the body?

Thanks

Mutt
