The Elite 750 Basic Universal Wire-in Harness ships with flying leads, so you terminate each wire to your own sensors, injectors, coils and power. The wiring diagram is your map: it shows each wire's color, which ECU pin it comes from, and what it's meant to connect to. It also comes in the Elite 750 + Basic Universal Wire-in Harness Kit.
Keep it beside you for the whole install, and check these before first power-up:
- Main power, grounds and the relay feeds, since these cause the most no-start problems.
- Trigger and home wiring and the shielding around it.
- Injector and ignition outputs in firing order, and whether your coils need igniters.
- Which inputs and outputs are still spare for extra functions.
The basic harness is a simpler loom than the premium version, so use the right diagram. For every pin, see the Elite 750 complete pinout.
