In the picture above, you will see the stock transmission bracket, which will need to be removed to install the 2nd CAI pipe. You will need to remove the reverse light sensor (top right in the picture) before you can remove the stock transmission bracket. To do this, you will first need to unplug the wire from the sensor, and the wire from the transmission bracket. Simply press the release button to unplug the wire, and use a needle nose pliers or a flat head screwdriver to unclip the wire from the transmission bracket. To remove the sensor, use a 27mm deep socket and unscrew counterclockwise. There is a washer between the sensor and the transmission, be careful not to drop it, and take care not to dent or scratch the reverse light sensor. After removing the reverse light sensor, you can now remove the two bolts (12mm) holding the bracket to the transmission. You will also need to remove the bolt on the transmission ground cable (10mm), and the clutch line bracket (10mm). After that, you can take the stock transmission bracket off.

The picture above should be pretty self explanatory, simply place the bracket as shown, and use the 19mm nut to secure it, make sure its torque down enough. (At least 20 lbs.-ft of torque) AEM's instruction calls for the removal for the stock transmission nut which would have required 40 lbs.-ft of torque and a 19mm deep socket, and I have come across some people that did not torque the original nut back in place enough, which resulted into the eventual cracking of the bracket or nut. Place the transmission ground cable onto the left side of the bracket as shown and bolt it into place. Do the same for the clutch line bracket, but do not tighten the bolt all the way down, as we will use this for a mounting point.

At this point, you can install the upper pipe by using two of the hose clamps, and one of the blue couplings. Place one hose clamp on the top of the coupling, and one of the bottom. Either use a flat head screwdriver to tighten the hose clamps, or a 8mm socket wrench. You should not tighten the top hose clamp completely, since you will need some adjustability for the 2nd intake pipe.
