Applicability

Controllers, harnesses and installation parts

ECU, power and protection

Start with the ECU, main relay, fuses and grounds. Then add pumps, coils and solenoids. Their current and driver requirements determine whether an ECU output can control them or needs a relay or power module.

Sensors and their controllers

List crank and cam triggers, pressure, temperature, position and lambda measurements. Each needs the right supply, ground, input and calibration. An LSU wideband probe also needs control electronics; it is not an analogue-output module.

Interfaces and verifiable functions

Mark which connections use loose terminals, flying leads or a finished harness. Add the PC interface, CAN devices and logging. For each function, identify its input, output driver and a way to test it.
