How To Change thermostat

[Sissy53]

I have an Escalade by KZ and need help puttering ng a new thermostat in. There are 2 main wires coming out of the rv. One smaller wire has 3 wires, red green and white. The larger wire has 5 wires yellow white green blue and red. It is a Coleman unit with heat pump. The Coleman thermostat has 6 wires red blue yellow white green and gray. Does anyone know how to connect this? Thanks so much.

On many of my TT's over the years I found you must buy the thermostat to match the brand of your unit. Coleman unit with Coleman thermostat, etc.
