STEP 41: Replace the factory connector with the provided mating connector. Please review the following information before proceeding to STEP 42.

The factory harness connector will need to be replaced by using the new mating connector provided with the throttle body jumper harness. The location of the connector to be replaced is identified in Figure 1, referred to as C1449 (in RED).

Identify the correct connector using Figure 2 below. This connector will be replaced with the connector shown in Figure 3.

Replacing the Factory Harness Connector:

The use of a pin extraction tool is recommended for this process. If you do not have a pin extraction tool, you may use a very thin screwdriver such as those used for repairing eyeglass frames.

TO INSURE THIS PROCEDURE IS DONE PROPERLY, IT IS HIGHLY RECOMMENDED TO SWAP ONLY ONE PIN AT A TIME!!

STEP 41A: Unplug the factory connector from the throttle body. The red locking tab on the factory harness connector must be released to do this.

STEP 41B: Gently pry the red retaining lock from the factory connector to reveal the female terminals.

STEP 41C: Starting with Pin 1, carefully pry back the plastic retaining tab (which holds the female terminal into the connector housing) while gently pulling on the wire from behind until the terminal has been released.

STEP 41D: Completely remove the wire and terminal from the factory connector.

STEP 41E: Prepare the NEW replacement connector for terminal insertion by removing the red retaining lock from the connector. Like the previous connector, this lock can also be removed by gently prying out.

STEP 41F: Insert the terminal (from STEP 41D) into the NEW replacement connector noting the orientation of the terminal. A locating tab on the terminal will allow the terminal to insert in only one direction. DO NOT FORCE!

NOTE: When the terminal seats properly, you should hear a light clicking sound. Gently pull on the wire to insure that it has seated properly into the NEW connector housing.

STEP 41G: Return to STEP 41C, and follow the same sequence for Pin 2 through Pin 6. Once all six terminals have been moved, replace the red locking tab (previously referred to in STEP 41E).

STEP 41H: After the NEW connector has been attached to the engine harness, connect the new jumper harness and route to the new throttle body’s Throttle Position Sensor (TPS) and Electronic Throttle Control (ETC) motor. There is a fir tree clip that will allow the harness to be securely fastened to the cylinder head.

When properly assembled, the factory wire colors should match the connector as follows:

STEP 42: Clip the provided jumper harness into the newly installed mating connector.

STEP 43: Clip the remaining (2) connectors on the jumper harness to the throttle body.
