Stick your head up in where the passenger's feet normally go. Near the firewall where the ECU harness comes through from the engine bay you'll see a white connector (about 2 pins by 8 pins in size) from the body harness. Make sure it's plugged into it's mate on the engine harness. It can be tough to see, you literally have to get your head all the way back there. If you sit in the passenger seat, it's located in the far right back corner, underneath the dash and tucked up out of the way.
