2010 Camaro Plate System Install
The 2010 Camaro runs pretty well but its heavy curb weight leaves many car guys and gals wishing for more power. Increased performance and quicker acceleration is quick and easy thanks to Nitrous Express. The following article outlines the installation of the Nitrous Express LS3 / L99 Plate system on the NX Energy Drink 2010 Camaro SS. This Camaro is equipped with an automatic transmission and the L99 engine. First off, we recommend disconnecting the negative cable from the battery in the trunk. Remove the engine cover by pulling up on the front of the cover (the oil cap must be removed as well). The next step is to remove the Air intake tube from the throttle body.

Unplug the harness from the throttle body and remove the four bolts that attach the throttle body to the intake manifold.

Apply a thin bead of silicone to the mounting flange of the throttle body.

Place the nitrous express plate between the intake manifold and the throttle body and reinstall the factory bolts.

Once all four bolts are tightened, rotate the throttle blade open and verify that silicone has not protruded into the throttle body bore. If needed, wipe excess silicone out with a clean paper towel. Now plug the Throttle body harness back into the throttle body and replace the air intake tube.
The next step is to remove the Schrader valve from the factory fuel rail (use an absorbent rag to catch any fuel that drips from the fuel rail). Attach the short braided fuel line (the one with the red fittings) to the factory fuel rail. Slip a fuel jet into the fitting on the NX nitrous plate and attach the fuel line to the plate. The next step is to run the Nitrous line through the vehicle. There is an unused rubber grommet on the driver’s side firewall (above and to the right of the hood pop cable). Remove the grommet and cut a hole large enough for the nitrous line and a few electrical wires to route through. Slip the nitrous jet into the plate and connect the nitrous line over the jet.

Route the nitrous line along the top of the intake, behind the insulation on the firewall, and through the firewall grommet. Next we’ll move to the interior. Remove the driver’s side plastic kick panel and door guard. Tuck the nitrous line below the carpet and route to the back of the vehicle.

Remove the lower back seat by pulling two clips at the bottom edge of the lower seat cushion. Route the nitrous line below the back seat bottom and under the back cushion. Attach the bottle brackets to the bottle and set the bottle in the trunk with the valve facing forward.

Mark the carpet through the holes in the bottle bracket. Remove the bottle and drill holes through your markings (make sure to check for wiring above and below the metal before drilling). Attach the bottle brackets using the supplied bolts, washers and nuts. Slip the bottle into the brackets and tighten. Also attach the main feed line to the bottle and slip any excess feed line below the carpet. Now it time to move on to wiring. Attach an 18 gauge wire to the purple wire of the Camaro throttle body harness (AKA TPS Wire) and route it through the previously mentioned firewall grommet. Make sure to solder and tape the connection.

Next we’ll wire the NX solenoid relay. Attach one wire of each solenoid to ground

and attach the other wire of each solenoid to the green wire of the NX relay harness.

Attach the white wire of the NX relay harness to ground (optionally through a fuel pressure safety switch). Connect the black wire of the NX relay harness to the positive battery stud on the driver’s side of the engine bay (we chose to install an optional fuse between this wire).

Next we’ll run the red wire of the NX relay harness (AKA relay trigger wire) through the previously mentioned firewall grommet. Cover the wires with split loom and electrical tape for a clean factory look. Replace the engine cover and oil cap.

We are now done under the hood so we’ll move back into the interior of the vehicle. Lift the shifter trim panel and expose the wires of the lighter plug.

Attach an 18 gauge wire to the red wire going to the bottom of the lighter plug. Make sure to solder and tape the connection

Route this wire behind the console and to the input of your master arming switch (we chose to place our master arming switch in the A-pillar).

Run a wire out of the master arming switch to the red wire of the NX throttle position activation switch. Connect the pink wire of the NX throttle position activation switch to the red wire of the nitrous system relay (AKA relay trigger wire) that you previously routed through the firewall. Now connect the white wire of the NX throttle position activation switch to the purple wire from the throttle body harness (AKA TPS wire) that you previously routed through the firewall. Ground the black wire of the NX throttle position activation switch to a chassis ground. Now it’s time to replace the trim panels and rear seat. Reconnect the battery, turn the ignition switch and master arming switch on. Now you must program the NX throttle position activation switch by holding the button down for 5 seconds and flooring the accelerator petal twice. Your system is ready to run.

The final outcome is a super clean nitrous install. The throttle body maintains stock location and the engine cover fits perfectly.
