These Painless Performance GM Gen IV Vortec truck engine wiring harnesses are designed to operate any Chevrolet Gen IV engine coupled with a 4L65E, 4L70E, 4L80E, or 4L85E automatic transmission. They cannot be used with a 4L60E transmission because it's missing the input speed sensor required by the transmission control module. The harnesses support engines with or without cylinder deactivation and/or variable valve timing. They utilize a factory-style ECM and TCM and feature an integrated weatherproof fuse block. Painless Performance GM Gen IV Vortec truck engine wiring harnesses have 10 fused power circuits, including ECM/DLC, injectors, ignition coils, oxygen sensors, ECM ignition, MAF/VLOM, and fuel pump. They also use an integrated 30 amp fuel pump, 40 amp cooling fan relays, and two ignition relays. The harnesses have an extra 4 ft. of length between the ECM connections and the main engine breakout.
