Wiring Harness🔗
This section outlines the available harnesses for CORE. See the Electrical Schematics section to view all four main electrical schematics.
Terminated Gen III Drive-By-Cable LSX CORE ECU Harness🔗
On this harness the knock sensors are located in the valley. The MAP sensor and Cam sensor are located on the back of the engine. EV1 and EV6 connectors can be purchased with this harness to allow usage of the OEM connector style Gen III LS application.
Note
- The EV6 injector is standard on the Gen III Drive-By-Cable harness.
- The Gen III Drive-By-Cable harness is wired for 2 Bosch 4.9 LSU (Laser Sensor Unit) sensors.
- Can 1 and Can 2 come pre-terminated with DT (Deutsch) connector for easy use with aftermarket products.
- 20 pin I/O expansion connector is standard for the Gen III Drive-By-Cable harness. It can be paired with either additional I/O flying lead harness or 4L60e/4L80e expansion harness for direct plug in and play to the 4L60e and 4L80e transmission setups.
Terminated Gen IV Drive-By-Wire LSX CORE ECU Harness🔗
This harness has an electronically controlled throttle body, along with an accelerating pedal feeding a signal to the ECU to control the electronic throttle. On the Gen IV Drive-By-Wire harness the MAP and Cam sensor are both located on the front of the engine. The knock sensors are located on the sides of the engine, which is different from the Gen III Drive-By-Cable harness.
Note
- The EV6 injector is standard on the Gen IV Drive-By-Wire harness.
- The Gen IV Drive-By-Wire harness MAP sensors wiring is long enough to go to either front or rear of the intake manifold.
- The Gen IV Drive-By-Wire harness is wired for 2 Bosch 4.9 LSU (Laser Sensor Unit) sensors.
- Can 1 and Can 2 come pre-terminated with DT (Deutsch) connector for easy use with aftermarket products.
- 20 pin I/O expansion connector is standard for the Gen III Drive-By-Cable harness. It can be paired with either additional I/O flying lead harness or 4L60e/4L80e expansion harness for direct plug in and play to the 4L60e and 4L80e transmission setups.
Unterminated 15’ Flying Lead CORE ECU Harness🔗
This harness comes with the four ECU connectors along with the 15 ft sections of wiring already pinned for the ECU connector. This kit provides cavity plugs for the cavities not being used.
4L60E/4L80E Transmission Control CORE ECU Sub Harness🔗
This is a single plug-in solution harness for the 4L60e & 4L80e transmission. Below outlines the 4L60e & 4L80e harness pinouts and I/O type.
