data port problem with X3

The local SCT guy just left. He was trying to do a flash tune so I can get rid of my chip. In the process the program tells you to turn off the key and turn it back on. It then says there is no power to the key or something similar. There are 7 wires to the port. My ford wiring diagram only shows 3. As this is a homemade harness, a Cobra in a 95 Ranger, I think I must have left a wire out. Where can I get a diagram that shows all 7 wires? It seems to run fine with the chip in but we want to use the X3 to fine tune the motor. This is brand new. Oh, I have a ScanGauge which seems to work for all the real time gauge info and scanning. Thanks, harry
