Servo Board 5 Connections, what are the called?

[onsatmex5]

I am a novice but trying to learn...I have uploaded a couple of photos of my current servo board.

And I am in the process of trying to install a new 6215h cambridge scanning system.

I don't know exactly what these 3 wires are referred to meaning I know one is the +input one is the -input and one is the -/+input return
I just don't know which one is which the red black and white wire's

How do I find out what the function of each wire is??

Also the other 2 wires near the top of the board I have no Idea what these are lol sad I know...but I do not know where to start...so here I am!

I have not been able to find anyone in the state of Maine that works on laser projectors...and I really don't want to ship my system out, so I am trying to do it myself

I also uploaded a couple of photos of the new 6215h scanners and the 673XX Servo board just for fun

Thanks for any help
