rear wiper switch wiring

[mattmac]

since i purchased this county the rear wiper has never worked and now i have to get a RWC i needed to sort it out- removed dash fascia only to find all the wires had been disconnected and tucked away behind dash-now i need to know which color wires go to which terminsal on back of switch-the terminals on back of switch are number 2,3,4 and then the one in the middle at the top. No.4 terminal has the short black wire that goes to top part of switch. hope that makes sense.
