Step 1 Disconnect negative battery terminal. If these instructions are followed closely, , this will prevent the CHECK ENGINE light from coming on after the installation.
Step 2 Unplug the throttle body electric motor, TPS, and mass air meter by sliding the red colored locking clips back, and then squeezing the tabs on each wiring connector while pulling them from their connections.
Step 3 Loosen the hose clamps at the throttle body and at the air filter box. Disconnect the PCV tube on the inlet hose by gently twisting the green locking tab and pulling the tube away from the hose and remove the intake hose from the vehicle.
Step 4 Unbolt and remove the throttle body. Note: be careful not to damage the throttle body motor housing as you will be re-using it.
Step 5 Using the T-20 Torx remove the motor housing, plastic capped spring, and TPS from the stock throttle body. WARNING! Do not attempt to rotate the TPS. It has a limited range of travel.Over-rotating it will destroy the internals and render the car undriveable. Step 6 Pop the removable circular cap off of the motor housing. (This is easily done with a finger .)
Step 7 Place the plastic capped spring over the end of the throttle shaft of the BBK throttle body and line the pigtail hook on the spring up with the catch slot in the gear.
Step 8 Install the motor housing minus the removable cap onto the BBK throttle body over the plastic spring cap and tighten screws.
Step 9 Using needle nosed pliers rotate the plastic spring cap COUNTER-CLOCKWISE (approximately 180°) until the 2 tabs line up with their matching landings in the motor housing, then gently pull up on the cap until it pops up into a latched position.
Step 10 Align the tabs on the removable cap with the slots on the motor housing and snap it into place.
Step 11 Install the TPS onto the BBK throttle body by lining up the locating tab and tightening the screws. Do not rotate the TPS! Just put it straight onto the throttle body.
Step 12 Check the throttle body for smooth action by opening and closing the flaps a few times with your fingers. You should feel a slight drag from the electric motor, but it should never bind or stick.
Step 13 V-10 truck applications- install the supplied adapter plate and all (4) supplied bolts. Refer to to engraving on adapter plate for corrrect mounting. GT 500- Install the throttle body onto the intake manifold using (2) of the shorter supplied bolts on the top mounting holes, and the original nuts on the bottom then re-establish the wiring connections.
Step 14 Re-install the intake hose and re-attach the PCV tube.
Step 15 Connect the (–) negative battery terminal
