The Elite 950 premium universal harness is a flying-lead loom: the ECU end is terminated and the engine end is left for you to connect to your sensors, injectors, coils and power. The wiring diagram shows what every wire in that harness does, by color and function, and how the relays, fuses and power feeds are laid out.
You'll want it open whenever you're terminating the engine side of the harness, adding sensors, or chasing a fault on an existing install.
Before first power-up, we check the following against the diagram:
- Battery power and grounds go straight to the battery, with every fuse and relay in place.
- Injector and ignition outputs are in firing order sequence, cylinder 1 first.
- Trigger and home wiring suits your sensor type.
- Sensor supply and signal ground wires aren't shared with high-current devices.
Make sure you're looking at the premium version, not the basic harness diagram. For pin-level detail, see the Elite 950 pinout and the Elite 950 overview.
