Did you turn power off before starting and do you have a meter for troubleshooting?

Attached 2 images. Let me know if you can see them. I disconnected everything so you can see my wires. Hopefully you can tell me how to connect.

I need a photo of the other end of these wires in air handler so I can see where they go.

Sir,
I am pretty sure that there is no way I can not get these screws off. Is this the only way that you can help me?

Do you have a volt meter to check between the RED and Blue wires to see if we have 24 volts AC?
