Vehicle Speed Connection
ECM Connector A, Pin 29 (Sends vehicle speed sensor signal) --> BLU Wire --> Connector C201, Pin 4 (on the 2006 Si) or Connector C202, Pin 10 (on the 2 door 2007 Si) --> BLU Wire --> Connector G, Pin 5 on the Under-dash Junction Box (located inside the cabin under the dash on the driver's side)--> Out of the Under-dash Junction Box via a BLU Wire coming out from Connector E, Pin 2 and a BLU Wire coming out from Connector D, Pin 2

Throttle Position Sensor
Throttle Position Sensor/Throttle Actuator (on the throttle body), Pin 1 --> RED/BLK Wire --> ECM Connector C, Pin 20 (Sensor Input (TPSA): Detects Throttle Position Sensor A Signal)...ECM does not output.

Throttle Position Sensor/Throttle Actuator (on the throttle body), Pin 3 --> RED/BLU Wire --> ECM Connector C, Pin 21 (Sensor Input (TPSB): Detects Throttle Position Sensor B Signal)...ECM does not output.

TPSA measures ~3.9V with the throttle fully open and ~0.9V with the throttle fully closed

TPSB measures ~4.1V with the throttle fully open and ~1.7V with the throttle fully closed

Great Thanks. But does this also aplies to R18's
