Description

2-Pin Nissan Auxiliary Air Controller Connector (Brown)

Suits the AAC (main idle speed control solenoid) on R33 RB25DET engines.

Also suits S14 and S15 SR20DET’s.

The idle control system on mid-1990’s Nissan RB and SR engines (among others) consists of an Idle Air Control Valve (IACV) unit, which consists of two devices – the auxiliary air controller (AAC) and the fast idle control device (FICD). In many cases, a third device, which is separate to the IACV, called an idle air regulator is also fitted.

This brown connector fits the AAC, which is the primary controller for idle speed. The AAC  receives a pulse width modulated (PWM) signal from the ECU and finely controls idle speed.

Connector comes with connector housing, terminals and seals.

Please check your original connector’s shape and keying before purchasing!
