Can I install without a control board?

I do not have a control board, only this mess of wires. Will it be possible to install it?

Make sure you label the wires coming from the furnace before disconnecting them, you wouldn’t want to switch the blue R wire with the blue G wire by accident.


Thank you this will be a huge help, kinda afraid to try this myself but I will get it installed soon.

Wow. This weekend’s group thank you goes to you sir. Wow.
