Any engineers/electronics experts here! I need help

Ok guys, I'm trying to build a motion timelapse controller for my slider.
Following this tutorial: http://www.youtube.com …=m5_ZQCQj7sg&fe​ature=plcp

I have a Intervalometer with a different plug instead of the 2.5mm on used in the video

I have the same servo controller.

Can someone help me figure out how to wire up my intervalometer to be the gatekeeper/ on.off switch similar to the one in the video. With out using the jack switch?
basically every time the intervalometer sends a shutter signal it would complete the circuit to the servo allowing it spin.

"Basically the Intervalometer is a simple switch (one for focus, one for shutter) that will turn on for a period of time and switch off when the timers say so. Using the shutter switch on the intervalometer you can use it to interrupt the motor on the slider and then control it however you wish.

You don't want current and voltages going through the intervalometer, so blocking the power wires from the batteries to the controller on the motor would not be advisable. The only other solution is to use the intervalometer to switch on and off the SIGNAL wire to the motor from the controller. This way, you can pre-set how fast and what direction you want the slider to move using the controller and then set the intervalometer to delay and pulse this signal on and off however and whenever you wish."

$10 to someone who can give me the simplest solution, with the most readily available parts that I could possibly salvage from my junk pile.

THANKS!!!
