Application:
The 122-1486 wiring harness is specifically engineered as a fuel injector wiring harness for Cater 3406E, 3456, C15, C16, and C18 diesel engines. These high-displacement powerplants are extensively deployed in wheel loaders (980G, 980G II, 988G), wheel tractor-scrapers (621B/G, 623B/G, 627E/G, 651B, 657B), excavators (385B, 5090B), articulated dump trucks (735, 740, D350E II, D400E II), track-type tractors (D8N, D8R II), and generator sets (SR4, SR4B, PM3456) . The harness functions as the internal injector harness connecting the electronic control module (ECM) to the electronic unit injectors (EUI), transmitting precise electrical signals for fuel injection timing and duration in engines operating under high-load construction, mining, and power generation applications .
