Nothing happens to the vehicle if you connect the negative side first.But is is safer to connect the positive side first.
Reason If the negative side is already connected and you put the positive side on you take a chance of touching a part of the body or radiator with your wrench while tightening it, causing the positive side to ground out.
If your negative side is not connected yet and you touch the wrench to the body while tighting the positive side nothing will happen.
So installing the positive side first reduces the chance of shorting the battery out which could cause the battery to explode.

Assuming neither battery is used to start the engine, simply connect the positive (+) terminal of the first battery to the positive terminal of the second battery.

Connect the load circuit to the positive and negative terminals of one of the batteries as usual.
