Just my battery and when tried start engine ABS, Brake and DSC light went on

I have some questions. When I was installing the battery I saw these two wires on the pic(one comes from the battery and other comes from CD changer area) but I didn´t know if they were plugged or not before the battery change. Anyway before I start the engine with new battery I conected the two wires. When I started the engine it run fine during one second and then went off. I try to start it again and same thing happened. So I decided to unpluged the two wires and start the engine again. It start it and remain at idle but these three lights went on. So now I don´t know exactly what to do. Did you guys that have change battery know what this wire is for? Can I assume they have something to do with the ABS, brake and DSC light went on?
For clearing some doubts I conected again this wire and started the engine again, and this time the engine was running fine but the lights remain on.
Will ABS and DSC lights went off if I re-install the battery again? Sorry for so many questions and thanks for any help.
