wiper help

[hotrodder]

I just re-wired my 66 with a aftermarket wiring kit. everything works execpt the wipers. the truck has 2speed wipers, and washers, but the washers nevr worked before. I still have the stock wiring harness from the wiper motor to the switch, but during the work one of the wires has broken from the connector. there is a yellow, blue, and either black or dark brown wires. the darker wire is still in the connector but the blue and yellow are just loose now. the kit has a wiper power wire, so how do I wire this back to working condition
