You just really have to watch the sensor wires, since they are angled it is easy to run them to the wrong side.

Not sure what year you have, but on my 2001 the front 02 have a flat 4 wire connector and the rears have a square 4 wire connector.

That's not good, fix it. The computer will be adjusting for the wrong bank.

The wires, as they come down into the tunnel area from their respective sides are as noted by Patches.
Re the fronts only; with stock exhaust manifolds it's close and fits great. When you install headers and O2 extensions you need to route the wires keeping them on the same side. Mine essentially went to the opposite side and turn back. As most headers have the bungs facing inwards, it's pretty much the only way.
The post-cat sensors cross over to the opposite side.
