Non ac heater box

Hey I just installed my non ac heater box and cant figure out what the red wire coming off the relay does. Can anyone help me. I did a search and couldnt find anything on the red wire.

The heavier gauge red wire into the relay should be a +12v source from the starter.

Do you know what the purpose of that wire is? Why would it go to the starter?
