03 GT sct issues

Whats up guys, Im new to this forum and was hoping maybe someone could help me out. Let me start off by saying I have an 03 gt with a jlt cai, longtubes, 78 mm throttle body etc.. I have the sct x4 tuner. I bought it from AM. I had no problems out of it for awhile but here recently it has become quite an issue. It will read dtc codes from my car but won't read the vehicle info or let my program my car. I keep getting general error codes. I called sct they said the problem was in the firmware. I sent the tuner in but when i got it back its still doing the same thing. So therefore i lost my stock tune. The tuner will read vehicle info off any other mustang except mine. I thought i could have possibly burnt up a ground so I found a couple of wiring diagrams and chased every single ground down that seemed it may cause an issue. Another thing my instrument panel lights only work when the switch is turned to turn on all interior lights. I used a volt meter to check the voltage going out and the problem seems to lie in the switch. My question is.. Could this have any effect on my pcm not releasing the vehicle info?.. I know the pats and pcm are all integrated together.. didn't know if that may effect something. The theft light constantly blinks off and on while the car is not running. Starts and runs perfectly fine.. Can someone help with this situation?
