The Ag Express JDRC3 to 12-Pin & 2-Pin Y-Adapter Harness converts the John Deere Rate Controller 3 (JDRC3) CAN connections to previous generation connector configurations, utilizing 12-pin Ampseal and 2-pin Molex connectors for seamless integration with older generation equipment and existing implement harnesses.
Designed to simplify rate controller upgrades, this Y-adapter harness significantly reduces the number of adapters required when installing the new JDRC3 on older generation equipment. By retaining existing constant power for implement receivers and preserving footswitch functionality for master switch operation, this adapter ensures full system functionality without complex rewiring or multiple adapter stacks.
Compatible with a wide range of Ag Express implement harnesses including AE3099, AE3065, AE3078, AE3173, AE3174, and AE3143, this adapter is manufactured to Ag Express quality standards and built for durability in demanding agricultural environments. It is ideal for rate controller upgrade projects, equipment retrofits, and service applications.
