Called dealer and told him I was hooking Integra to Raven 440 on NH3 rig. He had the app rate module but not the serial cable, 4000309-6. Ordered overnight and picked it up today. Get home and this is 4000315-6 for Rawson,Newleader mark III and IV,and Mid Tech. My question is, will it work? My inclination is no but other's on here are knowledgable enough to say otherwise. I already have switchbox and can stub. TIA, Craig

 Forgot to mention. The cable does have 9 pin serial so it will attach. I was concerned the wiring might not be right and mess up one box or the other.
