System32 harnesses have fusible links in the harness on all 12v supply wires.
Each injector and each coil pack power lead is individually protected.
The breaker requirement does not change. If a coil pack were to short out, it would pop its fusible link and not affect anything else. If an injector power lead were to short out, it would pop the fusible link for only that one injector.
The fusible links are located in the engine side circular connector backshell.
Thank you Robert. A tidy solution; my compliments sir.
