This should have a lot of information you need: http://www.sauservice.com/manuals/STW_html/stwmain.html . What cabinet do you have (upright, deluxe bench, or deluxe)?

In most cases, the majority of wires will only connect to one place, so you're pretty safe to just start plugging. I'd also do a sanity check when plugging in that both sides of the connectors have same color wires on each side (rarely do they change wire colors across connectors). The connectors are usually the same color as well.
