Need Wiring info for E350 Cruise Module

I have a 1990 E350 RV. The wiring plug that goes into the cruise control module had melted, and I need to know what wire goes to what pin. The pigtail is no longer available from Ford. It has 6 wires. The plug is located under the module just behind the radiator on the driver side. Anyone that could help and possibly include a pic would be appreciated. Pic could be as simple as:

Pin : 1 2 3 4 Front
5 6 Rear

1 White
2 Black
3 etc

Thanks Again
