Routing of Fiber Optics from Lights to Console?

Where are the location of the fiber optics that run from the lights to the center console on '68 thru '71's?
Are they part of the wiring harnesses? Or are they routed separately?

Thanks,
Steve

The rear one is part of the rear lamp harness, comes through by the radio antenna grommet at the back of the passenger compartment, then it splits off near the rear seat kickup panel, and follows the hump to run down the center to the console. The front one is part of the headlamp harness. It enters just under the fusebox and continues to the console.
