Technical Cable routing / wiring diagram Fiat Scudo II 2013

[PhilSchue]

Hello everyone,
I am looking for the cable routing or a cable routing plan for a Fiat Scudo II 2013. Specifically, I am looking for the cable routing from the junction box at the left rear light at the back of the car to the front. There a wiring harness dips into the body just before the wheel arch. However, it is not possible to see where and how it continues to the front or where the next transfer point is. I don't want to take the whole interior apart. Nobody at Fiat Professionell itself or at various authorised workshops has been able to help me so far.
If anyone here knows anything about this, I would be very pleased to receive any hints and tips. Thank you in advance.

Best regards

PS
I have found an "offer" for a workshop manual Fiat Scudo (2007-2016). Does anyone know this document and does anyone know if I can find the necessary information there?
