Heat Pump wiring 5 wires on thermostat 4 wires on heat pump

I asked this before and got some slack and some help. I'm retired so it's been years since I did this. I have 5 wires on thermostat 4 wires to heat pump. I'm changing out ac to heat pump and changing the wires would be next to impossible. Some said to use a Ecobee 4 to 5 wire fore heat pump. Now what would be best way to wire the thermostat to furnace and heat pump. Thanks for any help.
