My son was helping me with the HVAC box swap on my 94 W900L and he pulled the wires off of the trinary switch without a picture or marking them. Anyone able to help me with info about which color wires are attached to which posts?

Trinary Switch - Infinitybox
There is a diagram with wire colors, I think they are universal coloring so it may be easy to do.
