This paper presents a work carried out within the FULMEN lightning-on-aircraft oriented European project. It is the second part of the general presentation on the analysis of EM environment inside the aircraft. Therefore, it focuses on numerical calculations of voltage and current transfer functions on the ports of the same prototype wiring harness installed in several aircraft structures. The calculations have been carried out with the cable network CRIPTE code and rely on 3D field calculations performed by Ericsson Saab Avionics. The link between the cable code and the 3D code is achieved through the component of the incident electric field tangent to the running path of the wiring.
