New A/C delivered

Just got the new unit in and now looking at how I am going to install it and wire it all up. The unit looks great, but the optional Louvered Plenum Assembly is in gray and I will need to paint that to match. Also got the outside condenser coil that I will also have to install. Have not 100% figured out how it was untended to be wired up to the controls. The controls come with limited number of settings, Fan:L High, med, and low, and A/C or Heat. No adjustments for temperature.
