Thrower front handle wire placement

HI guys, can anyone tell me where the wire ran through on the real throwers, Ive seen that a channel can be cut under the front grip to run the wire under under, but where does it enter the housing when it comes out the body end of the grip, is there simply a hole drilled in the front of the housing on the movie ones for the wires to enter?

The neatest way would be for the wire to enter the grip tube under the grip and run through inside out of sight.

But im planning on using a pop out tip twist gizmo, so not sure if I run a wire inside through the tube wall if it will foul up the gubbins.

What do you guys do

Anyone able to tell me the correct route the movie cables went up the front gun handle please and how they entered the housing, need to know asap next thing to do :slight_smile:

Hole in the gun box:
