Heater Control Valve 94 318i

[impala]

1994 318i with climate control. The heater valve has 3 wires that plugs into it and they have came off. The colors are 1 yellow, 1 yellow with red stripe and 1 yellow with brown stripe. I need to know how they go on the plug. If someone has the same car or a electical diagram they could look at would be great! Thank You for the help
