ALL Unichip Questions / Problems

everyone keeps saying its a harness problem. y would it run at all if its a harness problem?
 
Im going to bring this back up a bit... I see there is a "unichip plug and play engine management" on protegegarage.. the words plug and play concern me.. and just with the flip of a switch you will get 10psi? and go from 175hp to 240hp? is this a good set up for $1000?
 
Don't get it from protege garage. I just bought the EXACT same thing from Auto Anything for $600. It came in last week and I opened it up and it's all there and will bolt right up. I also bought the tuner liscence from Unichip, so now I can tune it as well.
