Simplify your Caterpillar engine integration with the Kustom Truck Plug & Play Adapter Harness, a reliable solution for adapting from Cat 3126B, 3126E, C7, or C9 70 Pin engine electronics to Cat 3116 or 3126 engines with 40 Pin engine electronics. This adapter harness seamlessly connects the engine control harness from the firewall to the 40 Pin ECM, ensuring robust communication for heavy-duty applications. One end of the harness plugs directly into the 70 Pin engine control harness coming from the firewall, while the other end connects to the side of the Cat 40 Pin ECM, eliminating complex wiring modifications. Compatible with common 70 Pin ECM prefixes (3126B: 7AS, 8YL, 9SZ; 3126E: CKM, BKD, HEP; C7: KAL, WAX, SAP; C9: 9DG, LFE) and 40 Pin ECM prefixes (3116: 8WL; 3126: 1WM), this harness is ideal for mechanics and fleet owners performing engine swaps or upgrades on trucks like Kenworth or Peterbilt. Constructed with high-quality connectors and automotive-grade wiring, it offers durable performance and precise fitment. Note: The 70 Pin connection is at the ECM. Provide the last 6 digits of your chassis VIN and the engine serial number when ordering, and contact Kustom Truck for fitment confirmation to ensure compatibility with your chassis electronics. Enhance your engine integration with this precision-engineered adapter harness, crafted for durability and precision.
