LC1 hookup problem...Code 5

[Kidcamaro98]

alright well i hooked up my LC-1 today...im not using the little LED light and the push button because i dont need too. Well the lc-1 is brand new, i installed it once before to make sure everything worked and it did. Now i dont have the brown wire,yellow wire (analog 1 & 2) hooked up, or the black calibration wire that would be hooked up to the LED...well i hooked it all up and the sensor gets to about 65% warm up and then it says i have error 5. Is it because i need to do something with the black calibration wire?? Error 5 is short circuit sensor...but my sensor is Brand new...so whats the problem??
