You connect the positive post first and then the negative. I have been in the automotive industry for 5 years now and that is always how it is done. Reason being if you connect them the opposite way it can create a spark which is very dangerous due to the hydrogen gas produced by batterys. I recommend wearing safety glasses and wearing protective gloves.
