What planter? May not matter. 

In order to use the Seed Monitoring Module you will need the Field IQ master switch control. You won't need the section control box. You will need Cabling from the SMM to the planter Harness, and from the SMM to the Field IQ/750. Normally the SMM is back on the planter, but it wouldn't have to be. I'd talk to Cascade AG in Indiana. He's a good guy that's helped me out.
