Motorization

Here's a quick drawing of how it might be done. By putting the wiring into a flexible rubber line or some other type of tubing have it attached to a spring in the middle to the opposite wall. When the tray or amp rack is in the spring is pulling the tubing over to one side and when the tray is coming out the tube starts to straighten out but the spring is pulling against this so selecting the proper spring will be essential. If the tube is thicker than the thickness of the tray then it shouldn't get caught and want to roll under it and thinking about it find a tubing that will slide easily on the material you have chosen.

I used to work there. They have all kinds of actuators, sliding tracks, controllers, switches etc.

They even have a dvd you can purchase on how to build motorized amp racks.

One of the ways I have done it in the past is to leave slack and have the wires come up from the bottom center of the rack. This is the area of least distance the wires will move, without "bunching up" if I explained that correctly. Make sure thier is room under the rack as well, raise it a couple of inches so there is enough space for all of it regardless of the position of the rack.

Test a few times and secure the wires in a way where they won't bind or catch anything and you should be good to go.

best of luck.
