Help! Marcy Mach 2 personal trainer

I finally found a place for my old home gym so that I can supplement my free weights but I'm having a problem putting it back together. I got the machine together but I have no idea how to connect the  cables that work all of the stations and there is absolutely nothing on the internet for instructions. The original manufacturer apparently went out of business years ago. Is anyone here familiar with this system and how the cables connect? I could really use some help on this one. If anyone has a manual - I could REALLY use it.
