Hi there, I desperately need help. I am upgrading my IM-303 to a Retro M Instrasonic. I have two sets of 3 wires. Only five wires are used. Do you have any videos to show the new connections with the old wires?

Hi Eagle: Ah, No. I'm not an Intrasonic guy - you will need to contact them to get help with installing their equipment - Chris
