I am completing a Leopard 1A4 of Italeri, and I have mounted the pyrotechnical device over the gun barrel, as from the kit's instructions.
On photos, I have seen that a long cable starts from the rear of the support of the device, and arrives on the front or roof of the turret.
Now, I have found images on where the cable ends on older Leopard 1A2 and on Leopard 2s, but nothing on where it ends on the 2A4.
Could anyone help me on this?

Normally, the cable leads to the loaders periscope opening, the periscope is removed therefore.

Just as on Leopard 2. Thank you.
How does the cable connect to the rear of the device on the barrel? Should it enter into some box, or just enters into the rear plate of the thing?
