Hi. We bought a 2005 spx 3310 sprayer with a viper pro and aim command. It did not have accuboom when we bought it and we'd like to add it if we could. If I understand right we just need to get the node and the necessary cabling. My dealer says we'd need cable/wiring harness 117-1004-002 for that sprayer. He says they don't sell them anymore. Anyone know of where I could possibly look for one? Also if I can't find one what other options would I have for rate and section control? We currently are running trimble ez pilot for steering. Any help would be appreciated! Thanx!
