If that really is the case then I would suggest you send it back and get with Langmuir and try the razor weld 45 that is designed to be plug an play.
No matter what you will have soldering or cable splicing with any unit that is not designed for cnc and depending upon the unit you still may have to do that to get it to the right connector etc. to get into your LS cnc.
I am not sure how cheap you were able to get this but if tearing into stuff isn’t your thing I would just get one from LS.
