**Cam / Crank Angle Sensor: AEM trigger disc MUST be used
Discrepancies have been observed in the OEM cam/crank angle trigger discs between
model years and/or trim levels; to avoid confusion the Series 2 EMS does not support the
OEM Nissan trigger pattern. A replacement trigger disc is now included with every Nissan
EMS and must be installed before attempting to start the engine. The following installation
was performed on a stock Nissan S14 240SX so your installation may require removal of
more parts, but the procedure for the CAS disc change should be identical.

Tools/parts required:

• Replacement trigger disc for Nissan GA/KA/SR cam angle sensor

(AEM P/N 35-8760, supplied with 30-6600, 30-6601, 30-6602, 30-6610, 30-6611,
30-6620, and 30-6623 EMS)

• 8mm and 10mm socket with ratchet and extension
