Painless Performance GM Gen IV Vortec Truck Engine Wiring Harnesses
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 feature an integrated weatherproof fuse block. Painless Performance GM Gen IV Vortec truck engine wiring harnesses have 10 fused power circuits, including 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.
