The NSK system wiring diagram consists of an ECU (S98) and a wiring harness which connects it to the steering column where the motor (S99/1) and the potentiometer (S99/2) are fitted, to the battery (A1), to the speed sensors (K84), to the alternator signal A10 (for i.c. engine vehicles only), to the key lock (H1), to the warning LED (E50/1) and to the diagnostic and setting system (R10), where relevant.

There are two versions of the ECU, one for electrical vehicles (EAWCEC-G02) and the other for i.c. engine vehicles (EAWCEC-G04). The difference is that in the first case there is no signal from the alternator.
