Simplify your Caterpillar engine conversion with the Kustom Truck Direct Fit Adapter Harness, an economical solution for adapting from Cat ADEM2000/ADEM3 (70 Pin) chassis electronics to a Cat ADEM2 (40 Pin) engine. 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 (70 Pin) plugs directly into the ADEM2000/ADEM3 engine control harness coming from the firewall, while the other end connects seamlessly to the Cat 40 Pin ECM (ADEM2 engine electronics). Compatible with common Cat 40 Pin ECM prefixes, including 3406E (5EK, 1LW, 6TS, 5DS), C10 (2PN, 8YS), C12 (1YN, 9NS), and 3176B (9CK), this harness ensures reliable communication for heavy-duty applications. Ideal for mechanics and fleet owners performing engine conversions, this adapter offers durable construction and precise fitment. Note: This adapter is not compatible with trucks using factory smart gauges that rely on the J1939 datalink, as these require a new ECM-to-cab harness with a data processor. Confirm compatibility with your specific engine and chassis by contacting Kustom Truck for fitment verification.
