OBR 2020+ Ford 7.3 V8 Godzilla Engine Wiring Harness
Racing Use Only, Not Legal for Road Use
OBR engine wiring harness for the Ford 7.3L Godzilla, the same harness supplied in the OBR control pack kits. It comes with new OEM connectors and terminals for the sensors, injectors, coils, drive-by-wire throttle body, VCT and the oil pressure control valve, so nothing on the engine has to be modified.
Choose the version that matches your engine. Ford changed the 7.3 for 2023 (new intake, 86 mm throttle body, different coils and oil pressure sensor), and the two harnesses are not interchangeable:
- 2020-2022 engine: OBW187
- 2023 and newer engine: OBW253
Built by OBR in Livonia, Michigan, with aircraft-grade ETFE-insulated wire rated from -85°F to 392°F and resistant to fuel, oil and cleaning chemicals. The Y-split sits at the rear of the engine between cylinders 4 and 8, and the ECU lead is long enough to mount the ECU in the cabin or under the hood.
This is the engine harness only. For a complete setup with the ECU, power harness, wideband, TMAP sensor and tuning kit, see the OBR control pack for 2020-2022 engines or 2023 and newer engines.
For off-road and competition use only.
