Suit all TB48 Motors.
This harness connects to the main engine loom and connects to all of the 6 Injectors
it is common for this loom to go hard and brittle and sometimes the wires perish and break causing intermittent misfires.
This is a common fault and a good place to start if chasing a random misfire that comes and goes.
This is a Genuine Nissan Wiring Loom
