    Rated 5 out of 5 by from INSTALLED IN A 2013 SS CAMARO WITH AUTOMATIC TRANS I installed the MSD 2 Step 8733 in my 5th Gen 2013 SS Camaro with an automatic transmission.The installation was very easy under the hood. BUT, I attempted to connect the white activation wire to my brake light switch. I called the MSD tech line to ask them which color wire to tap into for 12 volts and they did not know. So I used a volt meter and discovered that there is no 12 volt source at the brake light switch. So I ran a wire to my rear brake light and tapped into my brake light. You might be able to tap into the 3rd brake light but I don't know if that will work for sure. Running the wire to my rear tail light was way more time consuming than the plug and play connections under the hood. I do highly recommend the 2 step though. Keep in mind, that, if you have a stock torque converter, you will not be able to bring up the RPM's very high without the tires wanting to break loose. I hope this review helps save you time.
