Painless Performance 2000 - 2002 GM VORTEC THROTTLE BY WIRE 60219 Manual Do Utilizador

  

 

 

Locate the tail section that you earlier separated from the engine group. Begin routing 

it towards the rear of the vehicle. Be sure to avoid all sharp edges, moving or hot parts, 
or anything else that may damage the harness. 

 
 

This circuit is used to power the back-up lamps. This wire will connect 

directly to the back-up light socket. You will need to splice a wire into this circuit in 
order to accommodate two back-up lights. 

FROM START SWITCH- This circuit is used to connect the start switch to the neutral 

safety switch. Connect this wire to a circuit from the ignition switch start position. This 
wire should only have power in the start position.

This circuit provides power to the electric fuel pump. Connect this wire to 

the positive side of the electric fuel pump. This wire only has power for a few 

INPUT SPEED SEN (optional) (not equipped on all models) – This connection is 

only used on the 4L80E/ 4L85E transmissions. This can be stowed if not needed.

OUTPUT SPEED SEN – The Vehicle Speed Sensor (VSS) is a pulse counter type 

output that informs the PCM how fast the vehicle is traveling. The VSS system uses an 
inductive sensor, mounted in the tail housing of the transmission, and a toothed 

reluctor wheel on the tail shaft. The teeth of the reluctor wheel alternately interfere 
with the magnetic field of the sensor creating an induced voltage pulse as the reluctor 

rotates. 

F. PNP– The Transmission Range Switch (PRND) switch is mounted to the side of the 

transaxle and is part of the Park Neutral Position (PNP) switch. The PRND switch is 
used by the PCM to indicate the actual gear selected. The PRND is made up of 4 

individual switches. The scan tool indicates ON or OFF for each switch depending on the 

position of the gear selector lever. The combination of ONs and OFFs will indicate the 
gear selected. If the combination of ONs and OFFs is invalid, a DTC is set. 

G. 

TO STARTER RELAY (optional) - This circuit is used to connect the neutral safety 
switch to the starter relay terminal #85. Connect this wire to the circuit in terminal #85 

of the starter relay. DO NOT CONNECT THIS CIRCUIT DIRECTLY TO THE 
STARTER SOLENOID. You can substitute Painless part #30202 (Hot Shot Relay) if the 

stock starter relay is not available. 

 

H.  TRANS– These circuits are used by the PCM to determine vehicle speed, gear position and 

control shift patterns.
