RV Repair: Duo-Therm Comfort Control Center, yellow fur, analog control

Question
I want to switch my Duo-therm analog control center to the digital. I brought a unit with no installation instructions. My old unit has 6 wire leading into it, where the new one has a 4 wire plug-in (telephone coupler type)This is the layout of the old wires (desc./ wire color) +7.5/Red , Cool/Yellow, Fur/White, Hi Fan/Blue, Fan/Orange,Gnd/Black . Any idea of how to hook-up?

Answer
I need to know the make/model of the one you bought and the current one if they have model numbers, most do. A model number on the A/C would also help. These can be nightmares if you cannot find schematics that are at least close to a match. I may be able to find some good info but I dont know off hand.
