Streamline your Caterpillar engine conversion with the Kustom Truck Plug & Play Adapter Harness, an economical solution for adapting from Cat 3116 or 3126 (40 Pin) engine electronics to Cat 3126B, 3126E, C7, or C9 (70 Pin) engine electronics. Designed for use when your existing engine control harness (from ECM to firewall) is in good condition, this adapter eliminates the need for a complete harness replacement. One end of the harness plugs directly into the 40 Pin engine control harness coming from the firewall, while the other end connects seamlessly to the Cat 70 Pin ECM. Compatible with common Cat 40 Pin ECM prefixes, including 3116 (8WL) and 3126 (1WM), and 70 Pin ECM prefixes, including 3126B (7AS, 8YL, 9SZ, 6PZ, 7JZ), 3126E (CKM, BKD, HEP), C7 (KAL, WAX, SAP), and C9 (9DG, LFE), this harness ensures reliable communication for heavy-duty applications. Ideal for mechanics and fleet owners performing engine conversions on trucks like Peterbilt, Kenworth, or Freightliner, this adapter offers durable construction and precise fitment. Note: This harness is specific to Cat 3116/3126 (40 Pin) chassis electronics and Cat 3126B/3126E/C7/C9 (70 Pin) engine electronics, with the 70 Pin connection at the ECM. Confirm compatibility with your specific engine and chassis by contacting Kustom Truck for fitment verification. Enhance your Caterpillar engine conversion with this precision-engineered adapter harness, crafted for reliability and cost-efficiency.
