ESP traction control light

Hi All,

I just installed a RoadHawk blackbox camera into my 197 using the 12v cig lighter yellow wire and a bolt as the ground. I unhooked the battery the whole time the electrics were played with but now turning the car on traction control is constantly turned off?

Anyone have any ideas?
 
I think its normal, drive it and turn the engine off and it will go off.
