Wiring for CMU and Easy C

I am trying to run the Easy C Tutorial 7 but have run into a wall. The code is written and downloaded to the RC but when we turn the power on, the pan servo turns completely to the left (if you're facing the camera) and jams. From then on, the pan and tilt mechanism does not move at all. My guess is that we have not set up the wiring correctly. Right now we have the tilt and pan servos hooked into their respective PWM ports on the camera sensor board, power going from PWM 16 on the RC to the power port on the camera sensor board, and the TTL connection is going from the TTL port on the camera sensor board to the ttl-232 chip and then into the ttl port on the RC.

Another debate came up with some members of my team... should the pan and tilt mechanism work with the servos connected to the sensor board or do they need to be connected to PWM outputs on the RC?

What exactly should the robot do if the code from tutorial 7 is correctly working? Should the camera pan and tilt? Should the robot follow the target light? Will it just move straight or should it actually turn the robot in the direction of the target if the target is off to the side? I just want to know what to expect if the code is working properly and we have everything hooked up correctly?

One last question... do we need to run the MPLab initialization stuff or does the default config file in Easy C suffice?
