Converting 8 wire plugin to standard receptacle

Hi how is everyone doing? I really don’t like asking for help but I really need it before I break my brain on this problem. My problem is I got a heat controller for my chemistry stuff for free it’s a really good unit rainin eldex CH150 only thing is it’s used to control a column. What I want it to do is control some thermolyne heat tape. What is stopping me? Well it was set up for a different plug that has 8 wires going to it and what I want to do is use a regular receptacle plug in to it so I can plug my heat tape to it to be controlled by it. Can anyone please help me out with this I’ll send pics so you can see the pcb and how I already screwed it up some by trying to do something I have no clue on what to do. I tried every electronic repair place here in Las Vegas and no one knows what to do or if it can be done
