SS100 Front Park Light Wiring

Hello

Can anyone please help with the location of the route that the wiring goes in order to reach the park lights on top of the front wings? If we look at the RHS, the wires are contained in a large conduit with other wires that passes across the chassis cross member just behind the radiator. They then appear to pass through a hole in the cross member on the RHS.

How do they then cross the RHS rail of the chassis and then end up in a smaller conduit that is attached to the inside of the wing/headlight support bracket?

Cheers Peter
