0.50 Cal Machine Gun power cable for Merkava Mk.3

[Sarawakia]

I am starting the Meng Models Merkava Mk.3 Baz with mine roller. I am trying to find out how the power cable for the solenoids on the 0.50 Cal on top of the main gun is laid out. I have found quite a few photographs on the net showing the arrangement on the Mk.4 but none for the Mk.3. My questions are:

a) how does the power cable go into the tank?

b) is the layout similar to the Mk.4, where the cable goes into the turret on the left, near the smoke grenade launchers?

Any photograph showing this will be most appreciated.

Many thanks in advance.
