Is the chip you're talking about the chip with the camera lense attached to it? We just used a standard serial cable, like the one used to program the robot and it fit fine. Are you talking about some other chip? What does it look like? Did you hook up the serial to TTL converter (small square board with 3 header pins) directly to the board? If so, try taking it out and connecting the three pins to a pwm cable and then plugging the cable back in the camera board. This should give you more room for the serial cable.
As for the power for the pwm, you don't have to write code to turn it on. The power is always there...the only thing you can change in the code is the pwm output which is the signal across the white wire. Hope this helps.
